ABSTRACT The combination of potassium (K) fertilization with the adoption of no-tillage (NT) increases the concentration gradient of K in the soil, requiring subsurface layers to diagnose fertility. This study aimed to evaluate the effect of K rates applied in band or broadcast on the soil K availability and soybean and wheat yield. The study was established in 2019 on a Latossolo (Ferralsol) in the northwest of Rio Grande do Sul State, Brazil, under NT since 2002. Summer soybeans and […]

ABSTRACT In an integrated crop-livestock system (ICLS), system fertilization exploits the nutrient cycling imposed by animal grazing and increases the system efficiency. An increasingly popular approach to fertilization in southern Brazil is anticipating P and K requirements for soybeans into the pasture phase. This can increase the use efficiency of these nutrients in ICLS based on meat production in winter and soybean in summer. This study aimed to evaluate the effect of fertilization strategy, grazing and soil acidity correction on […]
Soil physical attributes and soybean yield in an integrated livestock-crop system with different pasture heights in no-tillage
01/Aug/2007
The integration of farming and cattle production activities in no-tillage system areas with winter cover crops can be an income supplement for summer grain farmers. However, many of them are afraid of adopting this integration system, because of possible negative effects of animal treading on soil attributes, mainly of those related to soil compaction. This study was conducted: (1) to determine the alterations in the soil physical attributes promoted by animal treading; (2) to verify if the alterations in soil […]
Soybean and sorghum grain yield isopleths for liming and molybdenum rates
01/Jun/1998
Increase in soil pH by liming has been considered sufficient to assure Mo availability for crops. In soybean, the high response to liming might be related to additional demand of Mo for nitrogenase complex activity, in relation to other non-nitrogen fixing crops. Therefore, this research planned to study lime-Mo interactions for soybeans and sorghum crops, in a Red-Yellow Podzolic soil from the Mococa Experimental Station, Instituto Agronômico, State of São Paulo, Brazil, during the period 1985 to 1989. The treatments […]
