Organic manures and grasslands
Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1967In fertilisation programmes emphasis is usually given to the mineral elements and organic factors of the soil are neglected. Soil productivity is a function of both the inorganic and organic status of the soil and the latter warrants greater attention in Southern Africa.

Organic Manuring for Agronomic Crops
2019Organic farming is emerging as a popular way of growing healthy, safe, and nutritious food worldwide in a long-term sustainable way that cut the indiscriminate use of agrochemicals being used globally on the cost of environmental health and safety. Nevertheless, the growing population of the world requires increased food production for that use of ...

Green and Organic Manuring in Virgin Sandy Soils
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1974Summary In a field experiment carried out in a virgin sandy soil, the effect of green manures, bersecm (Trifolium alexandrinum) (BM) and gelban (Lathyrus sativus) (GM), and organic manures, dried sludge manure (DSM) and farmyard manure (FYM), on the soil micro-flora and some chemical properties, as well as on the maize yield, was investigated.

Enzymatic Characterization of Organic Phosphorus in Animal Manure
Journal of Environmental Quality, 2001ABSTRACTInformation on the forms of P present in animal manure may improve our ability to manage manure P. In most investigations of manure P composition, only inorganic and total P are determined, and the difference between them is assigned as organic P.

Managing manures in organic farming
Proceedings of the British Society of Animal Science, 2003Knowledge of manure composition is important for farm nutrient management, either if importing manure onto a farm or transferring nutrients around the farm in ‘home produced’ manures. Many factors affect the nutrient content of the manure ready to spread onto the land (Smith & Frost, 2000): dietary input and quality, nutrient losses during housing ...

ADSORPTION, COMPLEXATION, AND PHYTOAVAILABILITY OF COPPER AS INFLUENCED BY ORGANIC MANURE
Environmental Toxicology and Chemistry, 2003Abstract Copper (Cu) is bound strongly to clay minerals and organic matter in soils, and forms both insoluble and soluble organic complexes with organic carbon. In this experiment, the effect of five manure composts (biosolid, farmyard manure, spent mushroom, pig manure, and poultry manure) on the adsorption and complexation of Cu in a ...

Organic manures and mineral fertilizers
2007Until the mid 19th century organic manures were the only way of returning plant nutrients to soil and in some countries organic manures are still the principle source of nutrients. The increasing use of mineral fertilizers during the last 150 years has made a major contribution to increasing food production worldwide.

Organic Manures and Availability of Plant food
Madras Agricultural Journal, 1924It is well known that for nutrition all plants depend.upon the food material available in the soil and in the manure applied.It is therefore of some importance to determine how much of the food material in any manure becomes available when aded to a soil Food stufs are valued for their digestibility or availability of food material.the same is true of ...
