Abstract:
Abstract
In mid-southern US, cotton has been the dominant crop and was mostly grown in rotation with soybean. Reduction in cotton acreage over the past decade have resulted into growing soybeans in rotation with other crops including corn, sorghum and wheat. Diversified crop rotations can increase organic carbon and improve soil quality compared to mono-cropping systems. Therefore, the objectives of this study were to determine the effects of different rotational sequences on total soil carbon and total nitrogen in the midsouthern US. Field experiments were conducted at multiple locations in Missouri, Arkansas, Mississippi, Louisiana, and Texas from 2014 to 2016. The main-plots were crop rotations involving corn, soybean and grain sorghum under both irrigated and dryland conditions, whereas the sub-plots included residue management treatments where the corn residue was either left in place or burned. The results from these multi-location experiments will be presented during the conference.
