NERACA AIR UNTUK BEBERAPA TANAMAN BUDIDAYA PERTANIAN DI TAMAN FIRDAUS
Water balance provides an overview of the condition of water deficit or surplus. Water balance is closely related to climatic conditions, so climate greatly affects the water balance. In knowing the water balance, it is necessary to know the evapotranspiration value, in this study the evapotranspiration value is obtained using the Penman-Monteith equation using the CROPWAT 8.0 Model application…

Ultisol is known as a soil type with low organic matter and nutrient content, high acidity, and low fertility. This type of soil is usually deficient in essential nutrients such as N, P, K, Ca, and Mg. Therefore, organic fertilizers play a crucial role in improving plant productivity, especially in soils with low nutrient content. This study aims to analyze the effect of Liquid Organic Fertiliz…

Ultisol soils have low nutrient content, especially organic matter. One of the efforts to increase its fertility is the use of organic fertilizer from bamboo roots. Rhizobacteria in the root zone can fix free nitrogen from the air, increase the availability of N nutrients, and reduce N loss due to leaching. Compost plays a role in improving soil structure, while biochar can increase pH and reta…

Peatlands are ecosystems that have environmental functions, economic value, and ecological value. Peatlands are soils that form naturally from the weathering of vegetation that has grown on them over many years. Vegetation in swamp ecosystems can utilize the process of carbon anchoring to produce a lot of plant biomass both above the ground and on the surface. Oil palm plants are able to genera…

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…
