Liquid Organic Fertilizers for Sustainable Agriculture: Nutrient Uptake of Organic versus Mineral Fertilizers in Citrus Trees
The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer (mineral or organic) had significant effect in the nutritional status of the organic and conventionally managed mandarins.

متن کاملOrganic Fertilizers and Composts
Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...
متن کاملCarbon dioxide emissions from semi-arid soils amended with biochar alone or combined with mineral and organic fertilizers.
Semi-arid soils cover a significant area of Earth's land surface and typically contain large amounts of inorganic C. Determining the effects of biochar additions on CO2 emissions from semi-arid soils is therefore essential for evaluating the potential of biochar as a climate change mitigation strategy. Here, we measured the CO2 that evolved from semi-arid calcareous soils amended with biochar a...
متن کاملOrganic Manures , Composts and Artificial Fertilizers
Mineral Fertilizers. It is considered to be the hall-mark of the good agriculturist that he aims not only to produce maximum crops, but to maintain the fertility of his soil unimpaired for the benefit of posterity. Both these ends were achieved in former times by the use of animal manures, by fallowing at regular intervals, and at a later date by the practice of crop rotation in conjunction wit...
متن کاملIdentification of Diarrheagenic Escherichia coli Strains from Avian Organic Fertilizers
The Brazilian poultry industry generates large amounts of organic waste, such as chicken litter, which is often used in agriculture. Among the bacteria present in organic fertilizer are members of the Enterobacteriaceae family. The objective of this study was to detect the presence of diarrheagenic Escherichia coli (DEC) strains in avian organic fertilizer, and assess the potential damage they ...
