Good morning, everyone. I would like to walk you through a few slides. Let me start with the main operational and financial highlights of the quarter. 2013 has been a challenging year for our crops business in terms of weather. The main productive regions of Argentina have been impacted by an abnormal lack of rain.
The chart on the screen shows the rain distribution in the humid pampas and the Northwest region of Argentina compared to their historic levels. As you may see on the chart to the left, the humid pampas, or Argentine corn belt, was impacted by a severe drought during January and until mid-February. Rains during this period are critical for the soybean crop since the plant undergoes their first forming and grain seedlings [ph] at which point weather and climate peak. Therefore, the dry weather caused irreversible damage on the crop. Soybean second crop was also impacted in this region since the crop began its initial growth with very low humidity.
In the chart to the right of the page, you will see that the Northwest region also suffered from drought, which began in January and was extended until April. As a result, soybean first and second crops were negatively affected. In the case of corn, which is traditionally planted in September and undergoes a critical development during December, the impact on yield was less significant in rain levels during this month were good, as you may see in the chart.
As you may see on Page 3 of the presentation, the harvest of our crop is well advanced. As of the end of April, the harvest of wheat and sunflower was fully complete and rice was presently completed. [indiscernible] the previous crop season.
Wheat yields were 30% below the previous year and below our expectation. This is explained by the following reasons. First, yields during the previous crop year had been exceptionally good due to very good weather. And second, in the current season, above-average humidity conditions entailed the outbreak of a grain disease known as fussarium across Argentina and Uruguay.
In the case of rice, harvested yields were 5.7 tons per hectare, almost 5% higher than the previous harvest year. This yield increase is primarily a result of better rain distribution and temperatures for the crop. We believe there is a significant upside potential to our rice yields. We expect rice yields to gradually increase over the next 2 years as we continue with the transformation and zero-leveling process of our farms.
Regarding soybeans crop, as of the end of April, we harvested 48% of the crop. The harvest began in our highest quality farms, and as a result, partial yields were higher than last year. We expect final yields to be slightly below the previous harvest year as a result of the drought experienced during January and mid-February of 2013.
Moving to the right, you may see that 20% of the second soybean crop was harvested as of the end of April. We do not consider the yields observed over this small harvested area as a representative sample for the entire crop. Due to the drought mentioned in the previous slide, the lack of moisture prevented the normal development of the crop. Accordingly, we expect final yields to be slightly below the previous harvest year.
Lastly, 28% of the corn area has been harvested. Early corn planted in September grew under good conditions since the flowering period of this crop is in mid-December, where rainfall and soil humidity were adequate. Seeking to diversify crop risk and weather requirements, approximately 1/3 of our corn was planted during the end of November and beginning of December 2012. These late planted corn areas had good humidity conditions during their initial growth stage. However, plant flowering took place between early and mid-February and was negatively impacted by lack of rain. In aggregate, we expect final yields to be approximately 15% above the previous harvest year.
Let's move to Slide 4 to analyze the financial performance of the Farming business. Particularly in the crop segment, the decrease in sales was primarily driven by lower physical sales volume of wheat, as a result of a lower planted area and lower yields, as explained on the previous slide. On the other hand, rice sales increased by 36% as a result of the combination of 2 factors: first, a 5% increase in yields; and second, an 11.9% increase in planted areas compared to the previous harvest year. On a consolidated basis, total farming sales in the first quarter of 2013: wheat, $63 million, in line with those of the first quarter of 2012.
Moving to the bottom chart of the slide, you will see that despite the decrease in sales, adjusted EBITDA for our crops segment increased from $12 million in the first quarter 2012 to $14.7 million in the first quarter of 2013. The improved performance is mainly explained by a $6.8 million increase in the results generated by the mark-to-market of our hedge facility, which was partially offset by lower gains on changes in fair value, primarily as a result of an 8.8% decrease in planted area and lower volume yields and prices expected.
Moving to the right, you will notice that the adjusted EBITDA of our rice segment increased from $0.8 million in the first quarter of 2012. We have $4.6 million in the first quarter of 2013. This improvement is driven by the extension in planted area and higher rice yields. As a result, consolidated adjusted EBITDA for our Farming business reached to $18.8 million, obviously higher year-over-year.
Let's move to Page 5. During early May, we sold the Mimoso and Lagoa do Oeste farms located in Western Bahia, Brazil. The farms have a total of 3,834 hectares, of which 904 hectares are planted with coffee trees. Adecoagro will collect a total of $20.8 million for Mimoso and Lagoa including the coffee plantation. The selling price represents a 7% premium to the combination of the Cushman & Wakefield independent appraisal dated September 2012 plus the fair value of the coffee plantation in our balance sheet. In addition, the buyer will also operate 728 hectares of coffee in our Rio de Janeiro farm during an 8-year period for which Adecoagro will collect a total of $3.8 million. This transaction evidences Adecoagro's focus on return on invested capital.
Now let's move on to the Sugar, Ethanol and Energy business on Slide 6. The first 3 months of the year are commonly known as the inter-harvest season. During these summer months, due to favorable weather conditions, sugarcane plant growth is stimulated and less energy is stored in the form of sugar. As a result, mills suspend their crushing activities while their equipment undergoes maintenance in preparation for the upcoming harvest year. During the first quarter, mills also focus on the renewal and expansion of their sugarcane plantations.
During the first quarter of 2013, we planted a total of 6,321 hectares of sugarcane, slightly below the hectares planted in the first quarter of 2012. From this total area, 2,400 hectares consisted of new planted areas to supply sugarcane to the Ivinhema mill, which began its crushing activities in April of 2013. Additionally, 3,900 hectares consisted of sugarcane replanting to replace old sugarcane with new high-yielding sugarcane to maintain the productivity of our plantation. As of March 31, 2013, our sugarcane plantation consisted of 87,900 hectares, representing 24% growth year-over-year.
In Slide 7, you can see the financial performance of our Sugar, Ethanol and Energy business. As a result of the inter-harvest season, adjusted EBITDA in the first quarter only reflects the sales of sugar and ethanol inventory, the expenses incurred in sugarcane maintenance and preparation for the next harvest season, hedging results and overhead expenses. As shown in the upper left chart, net sales for the first quarter of 2013 were in line with the net sales of 2012. And in the right, gross profit increased from $8.7 million to $16.6 million. The improvement in gross profit is primarily the result of a lower cost for the sugarcane use as raw material to produce the sugar and ethanol inventory sold during the first quarter of 2013 compared to the first quarter of 2012. The cost of sugarcane transferred to the mill for processing is directly related to the price of sugar. The sugar prices during 2011 were considerably higher than in 2012. Inventories sold in the first quarter of 2013 were produced with lower cost sugarcane compared to inventories sold in the first quarter of 2012.
In addition, our operating margins were enhanced by the mark-to-market of our sugar hedge position. We have hedged 247,000 tons of sugar at an average price of $0.208 cents per pound of sugar [indiscernible] equivalent. Since current prices are below $0.18 per pound, our hedge generated a $9.6 million gain in the first quarter of 2013 compared to a $5.3 million loss in the first quarter of 2012.
Overall, adjusted EBITDA in the first quarter of 2013 was $15 million, $19.7 million higher than the first quarter of 2012.
Page 8 shows the evolution of Adecoagro's consolidated financial performance during the last 3 years. Consolidated adjusted EBITDA for the company increased from $1.8 million in the first quarter of 2012 to $29 million in the first quarter of 2013. Adjusted EBITDA margin in between period has increased from 1% to 28%. We expect our earnings and return on invested capital to continue increasing as our business continues achieving operational and cost efficiencies and our $10 million [indiscernible] is consolidated.
Moving to Page 9. Our debt outstanding at March 31, 2013 has increased by $54 million since the previous quarters for a total of $593 million. Long-term debt increased by $38 million, driven by the capital expenditures related to the construction of the Ivinhema mill. Short-term debt increased by $16 million. The first quarter of the year [indiscernible] working capital cycle since only a small portion of our crops are harvested and sold. And our Sugar, Ethanol and Energy business is getting ready to begin a new season. As we accelerate the harvest and selling phase in the second and third quarter, debt outstanding will be reduced. I would like to highlight that our debt structure is 66% in the long term. Our debt plan has decreased for the same reason from $218 million in the last quarter to $210 million as of March 2013. In aggregate, prior net debt stand at $383 million.
Let's move to the last slide. On April 26, 2013, Adecoagro celebrated the inauguration of the Ivinhema mill located in Mato Grosso do Sul, Brazil. Ivinhema is a milestone event in our consolidation as a leading producer of food and renewable energy. The construction of the first phase of Ivinhema was completed on schedule and on budget. The Ivinhema mill currently has 2 million tons of crushing capacity and will expand to 4 million tons in 2015 and 6.3 million tons in 2017. Together with the Angelica mill, our first mill completed in 2010, it will form a 10.3 million ton cluster surrounded by over 120,000 hectares of sugarcane plantation, which we believe will allow us to become one of the most efficient and low-cost producers of sugar, ethanol and electricity in Brazil. Ivinhema has successfully commenced the 2013 and '14 sugarcane harvest, and we expect to crush approximately 1.5 million tons of sugarcane, producing sugar, ethanol and electricity for the local and international markets.
Thank you very much for your time. We are now open to questions.
