1. INTRODUCTION
Soil salinity affects more than 935 million hectares globally, especially in arid and semi-arid areas, and represents over 20% of the world's irrigated territories. Intensified by climate change — through higher evaporation rates, changes in precipitation, and sea-level rise — and human activities such as the overuse of fertilizers and unsuitable farming techniques, soil...
Introduction
Excess use of mineral fertilizers can lead to eutrophication of rivers and lakes and biodiversity loss. Alternatives include the use of biofertilizers such as arbuscular mycorrhizal fungi (AMF). AMF form a symbiosis with most plant species, where they contribute to plant growth by providing essential nutrients such as phosphorus. However, the success of AMF inoculation is...
Soilless cultivation of plants during long-term crewed space missions will be essential to produce vital supplies such as clean water, food, and oxygen while sequestering atmospheric CO2. Fertilizer replenishment during these missions will be cost-prohibitive, so nutrients will need to be recycled from waste. Human urine is being explored as a source of nitrogen and phosphorus for plants, as...
1.Introduction
The future scarcity of phosphoric rock stocks is forcing to nutrient recycling at a societal scale by producing the so-called bio-based fertilizers (BBFs), allowing phosphorus (P) recovery and reuse in crop production. However, BBFs present a huge variability because they are produced from a wide range of agro-industrial by-products and different nutrient recovery techniques...
Organic winter wheat is characterised by variable grain yield and quality. To bridge the yield and quality gap while minimising the potential environmental impact, nitrogen management needs to be improved. The aim of the study was to examine how organic farmers can achieve the bread making quality of winter wheat by modifying their management practices. A one season field study was con ducted...
