Effect of fertilization in water quality and in zooplankton community in open plankton-culture ponds

Bioscience Journal, 2009
The effects of swine manure fertilization on the water quality of zooplankton-culture artificial in two ponds were measured a diel cycles in different months (October 1999, January and March 2000).

Effects of Agricultural Management on Water Retention via Changes in Organic Carbon in Topsoil and Subsoil

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Increases in soil organic carbon (SOC) through agricultural management can alter soil water retention. This is determined via changes in pore size distribution, namely, air capacity (AC), plant‐available water capacity (PAWC), and hygroscopic water capacity (HWC). However, it is uncertain how much soil water retention in topsoil and

Nitrogen fertilizer value of digestates from anaerobic digestion of animal manures and crops [PDF]

, 2011
After anaerobic digestion (AD) of manures for biogas production the concentration of ammonium-N is increased and the concentration of decomposable carbon in manure is decreased.

Agricultural Mulching and Fungicides—Impacts on Structure and Function of the Soil Microbial Community

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Plastic mulching and fungicides are frequently applied agricultural practices in strawberry cultivation, which may have an impact on the structure and function of the soil microbiome. Aim To understand their combined effects on soil quality, this study investigated the impact of the fungicides fenhexamid, cyprodinil, and fludioxonil

Substitutability of Livestock Manure for Chemical Fertilizer: A Contingent Valuation Analysis of Crop Producers [PDF]

The impact of new manure management regulations depends on the willingness of crop producers to accept manure. A contingent valuation analysis of crop producers was used to estimate the willingness of crop producers to accept or pay for manure.

Phosphorus Plant Availability of Biochars Derived From Contrasting Sewage Sludges to Ryegrass

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Although phosphorus (P) is an essential element for human life, it is currently sourced unsustainably primarily from non‐renewable phosphate rock sources. Sewage sludge pyrolysis is a method that concentrates nutrients in sludge, a large renewable P source, to produce a sustainable phosphorus fertilizer.
