Weed communities can be influenced by nutrient availability, form (e. g., ammonium vs. nitrate), amendment timing, type (e.g., organic inorganic), and immigration of seeds during applications. The objective this research was to compare the long-term effect different fertility treatments in a corn ( Zea mays L.)-alfalfa Medicago sativa L.) rotation on taxonomic functional structure composition w...

Is the production of “AnchoisFert” organic fertilizer via circular economy process based on omega-3 lipid extraction milled anchovy fillet leftovers with citrus limonene followed by mild drying economically and technically viable? This study answers this question identifies main obstacles, chiefly economic organizational nature, to be overcome prior commercialization new fertilizer. Along non-v...

In order to apply manure or compost to fulfill the nutrient requirements of a crop, knowledge of the amount of nutrients mineralized following application is needed. Nutrient mineralization from applied manure depends on temperature, soil moisture, soil properties, manure characteristics, and microbial activity. Since these factors cannot be accurately predicted, nutrient mineralization from ap...

Minable rock phosphate is a finite resource. Replacing mineral phosphorus (P) fertilizer with P-rich secondary resources is one way to manage P more efficiently, but the importance of physicochemical and microbial soil processes induced by secondary resources for plant P uptake is still poorly understood. Using radioactive-labeling techniques, the fertilization effects of dairy manure, fish slu...

It was pointed out in a previous report (1) that the inorganic composition of the pulp of Fuerte avocado fruit varies according to the availability of fertilizer elements in orchard soils. Fullmer (2) has shown for these same orchards that the petioles (leaf stalks) and leaf blades from trees in orchards that have received fertilizers containing phosphorus and potassium tended to contain higher...

The existing land characteristics and inappropriate management during intensive agricultural practice on upland, swampland, paddy field are the factors that causing productivity to be low decreasing. Alternative efforts increase land, rice, maize productivities could carried out through implementation of Site- Specific Nutrient Management technology based RAE parameter. This paper presents thou...

Essential plant nutrients contained in residues and wastes generated during biofuel processing can be recovered for further production of bioenergy biomass. The objective of this study was to determine the relative agronomic efficiency of “processed” biofuel residual (PBR). Liquid biofuel residual was “processed” by precipitating phosphate and ammonium in the residual with magnesium into a stru...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...

Phosphorus (P) loading from nonpoint sources, such as agricultural landscapes, contributes to downstream aquatic ecosystem degradation. Specifically, within the Mississippi watershed, enriched runoff contributions have far-reaching consequences for coastal water eutrophication and Gulf of Mexico hypoxia. Through storm events, the P mitigation capacity of agricultural drainage ditches under no-t...

Abstract Manure is a useful source of nutrients in olive orchards, but its effect on weed growth such an ecosystem has not been studied. A field experiment was conducted six-year old orchard (cv. Chondrelia Chalkidikis ) northern Greece to study the effects two forms fertilization (inorganic fertilizer and composted cow manure) weeds abundance flora composition (species diversity dominance). ra...
