1. Investigating Adsorption Capacities of Treated Sewage Byproducts for Their Potential Use As FertilizerAs the global population rapidly grows, food producers of the world are faced with the task of feeding as many as ten billion people by 2050. The current state of fertilizer use cannot support this growth, and the overuse and poor management of fertilizers has degraded soil, water, and air quality over time. The average recovery efficiency of nitrogen by crops is low, only 50% due to the fast dispersion/loss of applied fertilizers to the environment. This leaching of fertilizer often leads to... K.

2. Shining Light on Novel Pathways for Potassium Fixation in SoilCotton has a high demand for potassium, and potassium significantly affects both cotton yield and fiber quality. Thus, bioavailability of potassium from the soil is paramount. Bioavailability and leaching of potassium to crops and from soils has been studied since the 1940s. However, problems that confronted agronomists in the 1980s continue to impact growers and crop production, including unpredictable potassium bioavailability and inconsistent plant response to fertilizer application under a...
