  • Extractability, plant yield and toxicity thresholds for boron in compost

    Boron (B) is a trace element essential to crop growth in small soil concentrations (0.2-1.5ppm), yet may produce plant toxicity symptoms readily as the amount in the soil solution increases over 2ppm. Boron is present in significant amounts in recycled materials such as municipal solid waste (MSW) and coal fly ash, and therefore composts containing these ingredients may potentially exceed ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska

    Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

  • Using coir as a growing susbstrate - sustainably and ethically

    Manufactured from the inner husk of coconuts, coir is, but its very nature, produced in distant, and often developing, countries. This means that there is also an ethical slant to consider, as well as the question of shipping costs and carbon use. As retailers apply more pressure on their suppliers to focus on sustainability and ethics, these points are becoming increasingly important. Growers ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...
