Agroforest (AF) and short rotation coppices (SRC) are two techniques to bring forest vegetation in agricultural practice. To evaluate the effect of AF and SRC on carbon (C) and nitrogen (N) sequestration and changing of soil organic matter (SOM) quality the experimental agroforest sites, established in 2011 on agriculturally used soils, have been c...

Agricultural nitrogen (N) application to soils is the main source of atmospheric ammonia (NH3) emissions. Ammonia negatively impacts the environment on a large scale. These emissions are affected by spatiotemporal heterogeneities of parameters within the soil on a microscale. Some key parameters controlling processes of the N cycle are soil oxygen...

Nitrogen fertilisation contributes significantly to the atmospheric increase of nitrous oxide (N2O). Application of nitrification inhibitors (NIs) is a promising strategy to mitigate N2O emissions and improve N-use efficiency in agricultural systems. This study investigated the effect of NI, 3,4-dimethylpyrazol phosphate (DMPP) on N2O mitigation fr...

Climate change is one of the major challenges to global food security in the twenty-first century. There is a need to produce more food for the rapidly growing human population; however, this is being challenged by the growing anthropogenic pressure on natural resources and uncertain impacts of climate change on global agriculture. Generally, clima...

Excessive use of nitrogenous fertilizers and their improper management in agriculture causes nitrate contamination of surface and groundwater resources. This study was conducted along the seasonally flooded alluvial agricultural area of Indus River Basin to determine the spatial and temporal dynamics of nitrate concentrations in the groundwater alo...

Initial changes in soil structure and C stocks were studied under short-rotation coppices (SRC) planted on former cropland near Göttingen, Central Germany. Plantations were established either as monocultures with willow (Willow-SRC) or poplar (Poplar-SRC), or as an agroforestry system with willow strips and grassland alleys in between (Willow-AF)....

Greenhouse gas (GHG) mitigation strategies are often constrained by rice farmers' preferences, therefore an assessment of mitigation strategies taking farmers' constraints into consideration, are important for their possible adoption. The field experiments were conducted for two continuous rice-growing seasons in northern Vietnam, to evaluate the e...

Finding an efficient irrigation strategy that would minimize water consumption in rice cultivation is a key objective in dealing with the potential future competition for and scarcity of water as a resource. Several water-saving techniques have been developed, including dry-seeded rice and aerobic rice cultivation. This chapter explores these techn...

Maize (Zea mays L.) is considered as high nutrient demanding crop and needs balanced nutrition. It is also regarded sensitive to zinc deficiency. Zinc is mostly deficient in soils and application of zinc fertilizer is required to explore its full potential. Crop species and even cultivars within species vary in their Zn requirement. A field experim...

Short rotation coppices (SRC) as monocultures or as agroforestry (AF) applications (e.g. alley cropping) are two techniques to implement forest into agricultural practices. Despite afforestation promotes soil carbon (C) accumulation, age and type of the tree stand can affect the C accumulation in different degrees. Here, we studied the impact of af...

A field experiment was conducted during spring 2011 at Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan to evaluate the comparative efficacy of Zn uptake and grain yield in three maize hybrids namely Pioneer-32F 10, Monsanto-6525 and Hycorn-8288 through the ap- plication of Zn in the form of ZnSO4. The ZnSO4 treatments compr...

To investigate the allelopathic suppression of pearl millet (Penni-setum americanum L.), sorghum (Sorghum bicolor L.), guar (Cyamopsis tetragonolobus L.) and maize (Zea mays L.) by Achyranthes aspera L., germination bioassays were carried out under laboratory conditions. Aque-ous extracts of various plant parts with 5% (w/v) and of root with 1, 2,...

Maize is high nutrient demanding crop and needs balanced nutrition. Maize is also sensitive to zinc deficiency. Zinc is mostly deficient in our soils and application of zinc fertilizer is required to explore its potential. Crop species and even cultivars within a species vary in their Zn requirement. A field experiment was conducted during spring 2...

A field study pertaining to bio-economic assessment of maize-mash intercropping system at different planting patterns was conducted at Agronomic Research Area, University of Agriculture, Faisalabad during the autumn, 2007. Maize crop was planted in the pattern of 60 cm spaced single rows, 90 cm spaced double row strips, 90 cm spaced single rows and...
