The effects on sugarcane yields of deep tillage for land preparation on five different soil types in the coast lowlands of Natal are presented. Yields from the. rainfed plant and first ratoon crops indicate that, in general, there is little advantage in ploughing or subsoiling to depths greater than the conventional 20-25 cm. The only worthwhile response to deep tillage was obtained in a recent...

Inverse linear relationships between soil strength and yield in Coastal Plain soils that have subsurface genetic hard layers have previously been developed for corn (Zea mays L.), soybean (Glycine max L. Merr.), and wheat (Triticum aestivum L.) grown under management systems that include annual or biannual non-inversion deep tillage. In a field study in the southeastern Coastal Plains of the US...

Mechanical site preparation is frequently proposed to alleviate problematic soil conditions when afforesting retired agricultural fields. Without management of soil problems, any seedlings planted in these areas may exhibit poor growth and survival. While mechanical site preparation methods currently employed in hardwood afforestation are proven, there is a substantial void in research comparin...

Huang-Huai-Hai Plain is the most important region for grain production in China. In this area, long-term rotary tillage winter wheat and no summer maize have significantly increased soil bulk density, which impede root growth reduce yield. Subsoiling an effective practice to improve properties crop growth. The objective of study was investigate integrated effects subsoiling both seasons on spat...

Subsoiling has been acknowledged worldwide to break compacted hardpan, improve soil permeability and water storage capacity, promote topsoil deepening root growth. However, there exist certain factors which limit the wide in-field application of subsoiling machines. Of these factors, main two are poor quality high energy consumption, especially undesired tillage depth obtained in field with cov...

Studies on applying of soil management practices in the paricá and effects growth yield are essential to auxiliary its cultivation would allow us inform conservation decisions reconciliate biodiversity, wellbeing, sustainable production. This case study aimed evaluate at different practices, including consortium with an agricultural production, Brazilian Amazon. Paricá was implanted, consorted ...
