Ultisol soils are nutrient poor, especially nitrogen. Urea fertilization is often less efficient, so organic fertilizers such as humic acid and biochar are needed to improve soil fertility. This study aims to determine the effect of humic acid-biochar application and urea fertilizer on nitrogen nutrient uptake, growth, and yield of mustard plants on ultisol soil. This research was conducted in …

Plant growth and development depend on the availability of balanced nutrients, one of which is nutrients from a stable pH, which can make plants grow and develop optimally. If the pH is low, it causes low nutrient absorption, making the leaves yellow and growth slow, while too high a pH can cause plant roots to die. One of the plants that requires a balanced pH for its growth process is the Cym…
