The paper presents the study of influence ammophos, potassium magnesia and ammonium nitrate on content protein, gluten grain unit winter wheat using No-Till technology in edaphoclimatic conditions southern zone Rostov Region. It was shown that application mineral fertilizers to surface soil layer during cultivation improves quality. highest quality parameters (protein – 13.4% 25.3%, 780.0 g/l) ...

Crop growth models can be useful tools in evaluating the impacts of di€erent tillage systems on the growth and ®nal yield of crops. A tillage model was incorporated into CROPGRO-Soybean and tested for conditions in Ames, IA, USA. Predictions of changes in surface residue, bulk density, hydraulic conductivity, runo€ curve number, and surface albedo were consistent with expected behaviors of thes...

Introduction Conservation tillage has been one of the most rapidly adopted agricultural practices of the past 15 years (CTIC, 1983). The primary impetus for conservation tillage has been decreased soil erosion; fuel, labor, and machinery costs; and increased soil water storage and yields (USDA, 1975). Conservation tillage may be broad­ ly defined as tillage practices that reduce soil and water ...

This study had the objective of assessing the differences in foraging activity of the predacious ants between two areas, one conventional and other with no-till agriculture systems. The research was conducted in two contiguous 1.5 ha plots in Dourados MS, Brazil, from February 2001 to December 2003. Each plot received 750 baits (Nasutitermes termites), 425 at daylight and 325 at night. The term...
