Acta Horticulturae, 1992 Ten samples of rabbit manure representative of the different techniques of treatment and handling used by livestock farms in Catalonia have been characterized. Two of the materials with a different composition have been composted. The origin of materials influence the composting processes and the compost final characteristics ...

Spring barley yield and nitrogen recovery after application of peat manure and pig slurry [PDF]
, 2006 The effectiveness of peat manure, manufactured of pig slurry and moderately humified Sphagnum peat (slurry:peat ca. 1:1.5 v/v), as nitrogen (N) source for spring barley was investigated in a four.year field experiment on a clay loam soil in south-western

ToxicsThe main problem with the conventional plastics presently used is that they are too slow to degrade, and thus, accumulate in the natural environment. This situation occurs on farmlands because low-density polyethylene (LDPE) is widely used in agriculture.

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry [PDF]
, 2006 Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was

Recovery of Beef Cattle Manure Nitrogen in a Long-Term Winter Wheat Fertility Study
NitrogenBeef-cattle manure (BCM) can be an effective source of nitrogen (N) for crop production. However, N availability from manure can be difficult to quantify across varying environments. The Magruder Plots are a continuous winter wheat (Triticum aestivum L.)

INFLUENCE OF FERTILIZATION AND HERBICIDES APPLICATION ON SOIL MICROFLORA AND ELEMENTS OF SUGAR BEET YIELD [PDF]
Poljoprivreda, 2004 Two-year sugar beet trials were set up on two localities: Đakovo (Stagnic Luvisol) and Osijek (Dystric Cambisol). The soils showed acid environment respond (pHKCL 4.9 – 5.4) and low humus contents (1.3 – 1.6%).
