    The purpose of the research was to carry out an agronomic evaluation of the water and soil of the irrigation water board of the Chilla Grande / Generación de las Gascas community, in the parish of Toacaso, located in the province of Cotopaxi. The board is formed by 156 members, divided into 3 branches that connect the entire community. The objective of this research was to evaluate agronomically the water and soil parameters of the board. Water quality was assessed using multiparameter (electrical conductivity (EC), total dissolved solids (TDS), pH), and arsenic (As), total coliforms (nmp), Ce, and pH were evaluated in the laboratory. Samples were also taken in two branches where pH, nitrogen (N), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P) and arsenic (As) were determined. Also, the agroecological classification was studied, pending through QGis. In production, the most important crops for both consumption and points determined that the water has an alkaline pH, the EC is low, it does not cause damage to crops, the Sdt is not restricted for agricultural use due to its low levels, nmp is present in the irrigation water, contaminating fruits and vegetables. In the intake As exceeds 2.8 times its limit, in the reservoir it exceeds 1.3 times its limits, in branch 01 As exceeds 1.3 times its limit, likewise branch 03 it (0.7 times), according to Ecuadorian regulations (TULSMA). On the other hand, the results obtained from the soil quality of the joint, in branch 01 with a pH of 6.64 is a medium acid soil, while in branch 03 the pH was 7.03 (neutral). In the case of As, branch 01 concentrates 5.17 mg/kg in the soil, which is above the limits, while in branch 03 As with 1.43 mg/kg in the soil is below the TULSMA norms, in the soils of the two branches there is a high content of N, K, P, Ca, Mg. In the slopes, an area with moderately undulating slopes was obtained with 32,10%, with 19% flat or almost flat soils ans with 15,69% mountainous terrain. In the agro-ecological area, there are two types of soils, with 22,27% suitable for wildlife conservation and 32,10% suitable for permanent crops. The most important crops were identified through key informant surveys. As a result, the most important crops were potatoes (Solanum tuberosum), corn (Zea mays), beans (Vicia faba) and pasture (Pastus), which are also important for marketing. The As in the irrigation water is above the maximum allowable limits, which is accumulating in the soil and possibly contaminating the crops.
