Abstract

This research aims to examine the effect of variations in humus content on water retention and nutrient availability (N, P and K) in the soil. This research used a laboratory experimental design with humus content treatments of 0%, 2%, 5%, and 10%. The results showed that increasing humus levels significantly increased the water retention capacity and availability of soil nutrients. At a humus content of 10%, soil has the highest capacity to hold water and provide essential nutrients for plants. This shows that humus plays an important role in supporting the balance between water retention and nutrient release, which is very important for agricultural productivity. In conclusion, increasing humus levels through organic matter or green manure can improve soil quality and support sustainable agriculture, especially on land with low humus levels.

Abstract

This research aims to evaluate the effect of organic materials, fertilizers and planting techniques on plant growth and yield. Organic materials such as compost and manure are used to increase soil fertility, while inorganic fertilizers are applied to meet the macro and micro nutritional needs of plants. The planting techniques applied include legowo planting patterns, intercropping and monoculture with various variations in plant spacing. The results showed that the combination of organic matter and inorganic fertilizer significantly increased the soil nitrogen, phosphorus and potassium content, as well as the activity of soil microorganisms. The legowo planting technique provides better sunlight absorption efficiency, thereby increasing plant photosynthesis. Overall, the combination of organic materials, fertilizer and appropriate planting techniques resulted in more optimal vegetative and generative growth compared to the control. These results show the importance of integrating nutritional management and planting techniques to increase plant productivity in a sustainable manner.
