Soil fertility is the ability of the soil to provide essential nutrients in available form and in an appropriate balance. Mining often causes environmental damage, including decreasing soil quality…
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 st…
Ultisol is a type of soil formed in the tropics with low pH and relatively low nutrient content. This study aims to determine the effect of the combination of humic acid-biochar and urea fertilizer…
Soil is one of the important natural resources in the sustainability of plant life and environmental sustainability. The decline in the level of soil capability is indicated by soil erosion which c…
Soil fertility is the ability of soil to support plant growth by providing balanced nutrients. Low soil fertility makes constraints that can limit plant growth. This study aims to determine the sta…
