In order to explore the drag reduction mechanism of pneumatic subsoiling and study influence on soil, this used machine learning models predict working resistance a subsoiler adopted random forest (RF), error back-propagation (BP), eXtreme gradient boosting (XGBoost) support vector regression (SVR) analyze compare predictions these four models. Field experiments were carried out in two fields w...

The quality of sugarcane broth can be affected by soil management. In compacted soils the productivity is reduced, and raw material poor. This research aimed to evaluate for four management types: (CT) heavy harrow + light harrow; (CTI) Subsoiler (MT) (NT) no movement. variables investigated were resistance penetration (SPR), chemical (broth) crop yield. rows, SPR did not reach severe levels up...

A. 2004. Ecology and manipulation of bearclover (Chamaebatia foliolosa) in northern and central California: The status of our knowledge. Long the bane of foresters, but of interest to ecologists, bearclover inhabits thousands of acres of forest land in northern and central California. Little quantification of its recovery after disturbance is available because knowledge on the morphology of flo...

In Italy, there has been a significant increase of the areas cultivated with short-rotation forestry (SRF) poplar (Populus spp.) for the production of lignocellulosic biomass. This species has been generally introduced on soils managed with conventional farming practices that led to the formation of a hardpan. This constitutes a serious obstacle for root development and water availability, whic...

• Cover crops do not alleviate compaction in asparagus interrows. Straw mulch combination with shallow soil disturbance reduces compaction. Zero-tillage did increase asparagus. Field operations associated UK production (re-ridging and intensive foot vehicular trafficking of the wheelings) can result severe deep-seated interrows, impacting on crop health productivity. In this project, we investi...
