This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T.amancropping system. Four different tillage practices, namely, zero tillage (ZT), minimum tillage (MT), conventional tillage (CT), and deep tillage (DT), were studied in a randomized complete block (RCB) design with four replications. Tillage practices showed positive effects on soil properties and crop yields. After four cropping cycles, the highest OM accumulation, the maximum root mass density (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm soil depth), and the improved physical and chemical properties were recorded in the conservational tillage practices. Bulk and particle densities were decreased due to tillage practices, having the highest reduction of these properties and the highest increase of porosity and field capacity in zero tillage. The highest total N, P, K, and S in their available forms were recorded in zero tillage. All tillage practices showed similar yield after four years of cropping cycles. Therefore, we conclude that zero tillage with 20% residue retention was found to be suitable for soil health and achieving optimum yield under the cropping system in Grey Terrace soil (Aeric Albaquept).

Realizamos un estudio de campo durante dos temporadas consecutivas de cultivo de arroz para investigar el efecto de la aplicaci\u00f3n de fertilizantes qu\u00edmicos (NPK), NPK m\u00e1s esti\u00e9rcol verde (NPKG), NPK m\u00e1s esti\u00e9rcol de cerdo (NPKM) y NPK m\u00e1s paja (NPKS) en el estado de nutrientes del suelo, las actividades enzim\u00e1ticas involucradas en el ciclo de C, N, P y S, la comunidad microbiana y los rendimientos de arroz del suelo arcilloso amarillo. Los resultados mostraron que los tratamientos fertilizados mejoraron significativamente los rendimientos de arroz durante las tres primeras temporadas experimentales. En comparaci\u00f3n con el tratamiento NPK, las enmiendas org\u00e1nicas produjeron efectos m\u00e1s favorables en la productividad del suelo. En particular, el tratamiento NPKM exhibi\u00f3 los niveles m\u00e1s altos de disponibilidad de nutrientes, carbono de biomasa microbiana (MBC), actividades de la mayor\u00eda de las enzimas y la comunidad microbiana. Esto dio como resultado el \u00edndice de calidad del suelo (SQI) m\u00e1s alto y el rendimiento del arroz, lo que indica una mejor fertilidad y calidad del suelo. Se observaron diferencias significativas en las actividades enzim\u00e1ticas y la comunidad microbiana entre los tratamientos, y el an\u00e1lisis de redundancia mostr\u00f3 que MBC y N disponible fueron los determinantes clave que afectaron las actividades enzim\u00e1ticas del suelo y la comunidad microbiana. La puntuaci\u00f3n de SQI del control no fertilizado (0,72) fue comparable a la de los tratamientos con NPK (0,77), NPKG (0,81) y NPKS (0,79), pero significativamente menor en comparaci\u00f3n con NPKM (0,85). La correlaci\u00f3n significativa entre el rendimiento del arroz y el SQI sugiere que el SQI puede ser \u00fatil para cuantificar los cambios en la calidad del suelo causados por diferentes pr\u00e1cticas de manejo agr\u00edcola.

On the other hand, the increase in availability, innovation and application of these technologies could lead to the improvement of N use efficiency in agroecossystems and to the reduction of environmental impacts. The objective of this study was to quantify agronomic efficiency relative index, ammonia volatilization, and CO2 emissions from conventional, stabilized and controlled release N fertilizers in corn summer crop. The experiment was carried out in a corn crop area located in Lavras, state of Minas Gerais, Brazil, without irrigation. All treatments were applied in topdressing at rate of 150 kg ha-1 N. N-NH3 losses from N fertilizers were: Granular urea (39% of the applied N ) = prilled urea (38%) > urea coated with 16% S0 (32%) = blend of urea + 7.9% S0 + polymers + conventional urea (32%) > prilled urea incorporated at 0.02 m depth (24%) > urea + 530 mg kg-1 of NBPT (8%) = Hydrolyzed leather (9%) > urea + thermoplastic resin (3%) = ammonium sulfate (1%) = ammonium nitrate (0.7%). Thermoplastic resin coated urea, ammonium nitrate and ammonium sulfate presented low values of cumulative CO2 emissions in corn crop. On the other hand, hydrolyzed leather promoted greater C-CO2 emission, when compared with other nitrogen fertilizers.
