The agroforestry systems represent an option for smallholder subsistence farmers. The objective of this research was to study the organic agroforestry system of a peasant family in rainfed conditions in the community of Vicente Guerrero, municipality of Españita, Tlaxcala, to identify material flows, satisfying nutritional requirements of family and conservation of soil resources, to demonstrate their efficiency and impact on food sovereignty and create a possible model to replicate in similar agro-ecological conditions. Agroforestry system components were identified through field visits. The yields of each crop planted in 2011 and 2012. They estimated the carbohydrate and protein content of each crop to consider their total contribution and compare it to the human nutritional requirement was calculated. Samples of soil before planting and after harvest determined pH, MO, N, P and K. The agroforestry system studied has an area of one hectare, it is classified as "trees in farmland" presents a moderate slope, It has six terraces and five boards, has three components: agricultural crops (corn, beans, squash, tomatoes, oats, bean), perennial crops (13 species of fruit) and animals (chickens and horses). It turned out that organic crops agroforestry system in 2011 covered the requirements for carbohydrates and proteins 4.07 to 4.45 people. In 2012, they provided for 8.81 people carbohydrates and proteins to 10.85, the observed difference was due to a better distribution and increased availability of rain in that year.
