摘要：

The expansion of blue agave (Agave tequilana Weber) plantations beyond the plant's original distribution range in the state of Jalisco, Mexico, has caused a drastic change in land use and crop patterns, exerting pressure on natural resources. This study originated based on a request from landowners who leased their land to a tequila company to grow agave in the municipality of Autlan. Therefore, this study records the effect of crop management on the degradation of non-renewable soil and water resources in plots conventionally managed by the company compared to the one managed by a private owner The sampling unit was 2 m x 5 m runoff lots, with a repetition and a control lot (without vegetation cover) with a 6% slope. Sampling was carried out in the rainy season from July to October, 2020. The results showed different behavior between repetitions. Total sediment yield in the farmer's plot was 9.260 t ha(-1) and in its control 6.844 t ha(-1) versus the company's plot of 13.796 t ha(-1) and its control 5.233 t ha(-1). These values reflect an increase in soil loss by 26% and 62%, respectively, due to management effects. The difference between sites is due in part to the different rainfall intensities and distribution of recorded rainfall separates the two sites. Given these results, there is a lack of knowledge of the impact of crop management on soil degradation by companies and farmers who lease or plant blue agave, in addition to the absence of a sustainable project that considers the conservation of soil and water, based on agronomic and cultural measures before, during, and after the harvest season by the municipality and state authorities and the agave-tequila companies.
