Abstract:

The increasing need of land from year to year results in the narrowness of fertile and potential agricultural land. This condition causes an imbalance of land use, which can directly harm the agricultural sector. To be able to utilize land resources in a directed and efficient manner, it is necessary to provide complete data and information about land characteristics and land use requirements that will be cultivated. Information in the form of land characteristics and land use requirements is needed in land evaluation activities. Land evaluation conducted by using ALES program (autometed land

Abstract:

Pedodiversity is generally neglected in studies concerning soil organic carbon (SOC). Therefore, this investigation aimed to explore the effect of soil types on the following: (1) soil processes related to organic matter (OM) dynamics along the profile; and (2) the microbial community and functionality within the uppermost horizon. Humic Dystrudepts (HD), Typic Dystrudepts (TD), and Humic Lithic Dystrudepts (HLD) were selected in beech forests of the Apennine ridge in the Emilia-Romagna Region (Italy).

Abstract:

The palm oil industry is the largest economic supporter for the Indonesian economy from the agricultural sector. Behind the success story of this activity, there are environmental consequences regarding the decline in land quality as a result of improper land management. To study the effect of oil palm plantation management on soil fertility, a study was conducted in three locations, Dharmasraya Regency (Kanhapludult), South Solok (Dystrudepts) and South Coast (Haplohemists) in West Sumatra. Research data were collected from 2017 to 2022 respectively, and analyzed. The results showed that soil

Fe is an important micronutrient in enzyme activities, including cytochromes in the process of electron transfer, chlorophyll synthesis, and in maintaining the chloroplast structure. The research was conducted in 2 series of field observations. The first observation was conducted on the application of clay mineral soils (Plinthic Kanhapludults and Lithic Dystrudepts) in a silt pit, while the second observation was on the application of liquid nano-size
