Plant-soil relations may explain why low-external input (LEI) diversified cropping systems are more efficient than their conventional counterparts. This work sought to identify links between management practices, soil quality changes, and root responses in a long-term cropping systems experiment in Iowa where grain yields of 3-year and 4-year LEI rotations have matched or exceeded yield achieve...

Prediction of phosphorus (P) availability from soil-applied composts and manure is important for agronomic and environmental reasons. This study utilized chemical properties of eight composted and two non-composted beef cattle (Bos taurus) manures to predict cumulative phosphorus uptake (CPU) during a 363-d controlled environment chamber bioassay. Ten growth cycles of canola (Brassica napus L.)...

12 Complex relationships exist between different components of the organic farm and 13 the quantity and quality of the end products depend on the functioning of the whole 14 system. As such, it is very difficult to isolate soil fertility from production and 15 environmental aspects of the system. Crop rotation is the central tool that integrates 16 the maintenance and development of soil fertil...

A pot experiment was carried out in 2019 the net house of Department Soil, Water and Environment, University Dhaka, to evaluate growth yield Jute plants (Corchorus capsularies L.) by applying different types organic manures. Eight manures viz. ACI, BGF-1, Mazim, Vermicompost, Shufola, GTS, Green Poultry were collected from local market. The set up following a completely randomized design (CRD) ...

A Field experiment was carried out during Kharif season of 2018 at the research farm in Udai Pratap (Autonomous) College; Varanasi (U.P.), India. The site adjoining to Department Horticulture college. consisted Six treatments comprising combinations recommended doses organic and inorganic manures (FYM, Vermicompost poultry manures). laid a Randomized Complete Block Design (RBD) with six treatme...

The hypothesis that plants supplied with organic fertilizers are better defended against insect herbivores than those supplied with synthetic fertilizers was tested over two field seasons. Organic and synthetic fertilizer treatments at two nitrogen concentrations were supplied to Brassica plants, and their effects on the abundance of herbivore species and plant chemistry were assessed. The orga...

It has been previously argued that application of organic residues added in soils has a great impact on soil quality, grain productivity as well as greenhouse gas emissions. Substitution of chemical fertilizers has become a common practice in agricultural systems which consequently affect the greenhouse gas emissions from agricultural fields. To observe the effects of organic manures and crop r...
