Abstract:
<p> Weeds are one of the biggest challenges for organic growers because of the alternative weed control methods. Air-propelled abrasive grit management has been reported to control weed seedlings in corn and soybeans while maintaining yield. This research examined the weed control, corn and soybean yields, nitrogen mineralization, and nitrogen yield responses from grits. The grits used in this research included: Phytaboost Plant Food 7-1-2 (soybean meal), Sustane 8-2-4 and 4-6-4 (turkey litters), and two non-fertilizer grits: Agra Grit (walnut shells) and corn cob meal.

Abstract:
Composting is a sustainable method to deal with huge amount of daily organic waste due to its robustness and easy operation. However, food waste (FW) as the main material in composting has disadvantages such as the heterogenous properties, high foreign matters contamination, high moisture content, low C/N ratio, poor structure, low porosity and high acidity during the initial phase of composting. These shortcomings not only influence degradation efficiency but also cease the composting process. Therefore, a bulking agent is required to increase the porosity and adjust the moisture content as w

In cities today, vast amounts of nutrients are being wasted. Improvement in nutrient management within agriculture can contribute to a more sustainable society. Reusing nutrients in agriculture could aid in creating a more circular system, where organic fertilizers can be used instead of chemical fertilizers. Urine is a liquid which has a high nutrient content. According to the Swedish environmental protection agency, human urine can replace mineral fertilizers, by using methods such as source separation, where urine is divided from faeces.

Abstract:
Raw shrimp shells are selected as an alternate nitrogen supplement to improve the quality of empty fruit bunch (EFB) compost as an organic fertilizer. The composting of EFB and raw shrimp shells with POME was performed in laboratory scale at three different temperatures. Better characteristics and quality of EFB compost was obtained at 40°C. An empirical model was developed to represent relationship between nitrogen content of EFB compost and respective process variables

Além disso, os compostos organo-fosfatados podem apresentar características mais apropriadas ao clima tropical, com liberação mais lenta de P2O5 e ainda, acrescentando matéria orgânica nos solos, melhorando suas características físico-químicas e possibilitando um aumento de produtiv
