The impact of manure application in the organically managed crop rotation

Agraarteadus, 2018
Organic agriculture is a production system which relies on ecological processes. In the organic farming systems, it is important to improve soil fertility and to protect soil physical condition for its healthy functioning.

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Microbial Composition Change and Heavy Metal Accumulation in Response to Organic Fertilization Reduction in Greenhouse Soil

Microorganisms
Increased application of organic fertilizer is an effective measure to improve greenhouse soil quality. However, prolonged and intensive application of organic manure has caused nutrient and certain heavy metal accumulation in greenhouse soil. Therefore,

Selecting Promising Soil Quality Indicators for Monitoring Soil Management Effects Based on 10 European Long‐Term Field Experiments

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Soil quality can be measured through soil quality indicators that reflect soil processes. Aim: The aim of this study was to (1) identify a limited set of soil quality indicators that are most sensitive to agricultural soil management and that are widely applicable regardless of pedo‐climatic conditions, and (2) link common ...

Utilization of Halophytes as a Source of Organic Manure

International Letters of Natural Sciences, 2014
Organic farming is a holistic production management system that promotes and enhances environmental quality including biodiversity, bio-geo-chemical cycles and soil floral and faunal activities. One of the energy resources developed during recent years are the application of organic sources such as biogas slurry, blue green algae ...

Yield‐Dependent Allocation Functions Overestimate Root‐Derived Carbon Inputs in Wheat and Maize

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Root‐derived carbon (C) inputs for wheat and maize were estimated using the yield‐based allocation functions of Bolinder et al. and Jacobs et al. Comparison with measured root C showed systematic overestimation that becomes larger as predicted C increases.

Fertilizer impacts on soil aggregation and aggregate-associated organic components

Plant, Soil and Environment, 2018
A 5-year (2012-2016) field experiment was conducted to investigate the impacts of different fertilizer treatments (no fertilizer, mineral and organic fertilizer) on organic carbon and soil water-stable aggregates in a North China Plain Vertisol. Compared

CONVERSION OF ORGANIC MANURE INTO BIOGAS

Poljoprivreda, 2009
Production of biogas with anaerobic degradation from organic waste is one of the pledge alternative energetic solutions, especially from organic manure made from animal farming and other residuals of agricultural production. According to 2005 livestock manufacture data daily quantity of animal excrements in Croatia, based on LSU number, is 784 015.26 ...

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

Journal of Plant Nutrition and Soil Science, EarlyView.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.
