Agriculture is one sector that is still the mainstay of most Indonesians. Agricultural activities cannot be separated from the fertilization process. Most farmers think that the more fertilizer they provide, the better the yield will be. Excessive fertilization using inorganic fertilizers (especially P fertilizers) can increase the levels of Cadmium metal (Cd) in agricultural soil. Cadmium (Cd)…
The palm oil plant belongs to the monocotyledonous seed plants which have fibrous roots. At the start of germination, the first root emerges from the seed which germinates the radicle. After that the radicle will die and form the main or primary root. Furthermore, the primary roots will form secondary and tertiary roots. This study aims to study the distribution of palm oil plant roots in swamp…

Peat soils are soils formed by the accumulation of organic matter, which is constantly inundated mainly during the rainy season, and plays an ecologically important role in hydrology, carbon storage, and biodiversity regulation. The diversity of peatland vegetation is closely related to the formation of peat layouts. One of the supporting factors for vegetation growth is the stability of the ch…
Lebak swamp lands are swamps on the left and right sides of large rivers and their tributaries, with a flat topography, flooded during the rainy season, and dry during the dry season. Irrigation is the flow of water on the ground to help regulate the availability of water due to insufficient rainfall so that water can be optimally available for plant growth. Irrigation is an act of moving water…
Soil is a medium for receiving heavy metals. If the heavy metal content in the soil exceeds the threshold, the presence of these heavy metals will cause soil pollution and endanger human and animal life. One of the heavy metals that is dangerous and often pollutes the environment is lead (Pb). According to the Food and Drug Supervisory Agency of the Republic of Indonesia (BPOM), the heavy metal…
Sweet corn is one of the important food commodities in Indonesia. Sweet corn has various uses as well as can be used as a processed material in the manufacture of cornstarch and animal feed. Sweet corn is also in great demand by the community so that their needs increase as the population grows.
