Land suitability is the level of suitability of a plot of land for certain uses. Land suitability can be viewed from environmental quality, including climate, soil, topography, and drainage. The role of land classification and evaluation can provide alternatives for determining land suitability as well as information on the relationship between land characteristics and its utilization.This rese…
The use of ultisol for plant cultivation has obstacles in the form of low productivity and few nutrients. In order for ultisol productivity to increase, this can be done by increasing the availability of nutrients and improving the chemical properties of the soil by adding organic materials such as biomass, compost and wet ash. Sweet corn is a food that many people like because it has a sweet t…
Erosion is a natural resource problem that causes damage to the environment. If not controlled, erosion can cause a decrease in soil quality and have a negative impact on plant productivity. Based on these problems, this research aims to estimate the value of soil erosion on the Kebon Kito Lubuklinggau Agrotourism land. This study focuses on measuring erosion and the distribution of erosion haz…
Teh merupakan tanaman perkebunan dengan produksi relatif lebih cepat, memerlukan hara makro N, P, dan K dalam jumlah banyak untuk pertumbuhannya. Unsur-unsur ini diberikan melalui tanah, dan memiliki pengaruh signifikan terhadap produktivitas tanaman. Nitrogen, khususnya, memiliki pengaruh cepat dan nyata terhadap hasil pucuk. Kekurangan N dapat menyebabkan penurunan produksi teh. Fosfor, unsur…

Mulya Sari Village is a village located in a tidal swamp area. This tidal swamp has quite a large potential to be used as farming land if managed well. Groups of food crops and plantations such as rubber and oil palm are the most dominant commodities cultivated by village farmers. The group of horticultural crops, especially pineapple, is still very limited for cultivation in this region. There…
Tidal swamp land is land where sea and river water rises and falls which can affect the characteristics of the land. The level of crop production cannot be separated from the quality of soil fertility. Soil fertility is the potential of the soil to provide nutrients in sufficient and balanced quantities to ensure optimum plant growth and production. This research aims to determine the status of…
The mining sector is one of the biggest drivers of the economy and national development for Indonesia, including coal. Mining activities start from exploration, land clearing, topsoil stripping, overburden excavation, coal mining, transportation, processing and marketing of coal. The activity of stripping and removing top soil and rock layers has an impact on environmental damage, including los…
Coal mining is generally carried out with an open pit mining system or by stripping the soil covering the miningmaterial. Open-Pit Mining has a major negative impact on the environment, one of which is the destruction of the soil layer. As result plants cannot develop normally. The reflection of how easily ornot easily the soil is penetrated by plant roots is called soil resilience. Soil resist…
Global warming is a form of ecosystem imbalance on Earth caused by an increase in the average temperature of the Earth's atmosphere, ocean and land. As a result, carbon concentrations in the atmosphere increase and cause a greenhouse effect. Actions that can reduce global warming are to restore damaged natural conditions so that plants can absorb carbon dioxide for photosynthesis and then produ…
Evaluasi lahan merupakan proses analisis yang bertujuan untuk mengevaluasi karakteristik, potensi, dan kesesuaian suatu area lahan untuk berbagai tujuan penggunaan.
