As a result, the construction of dwellings as well. Area for agriculture is diminishing. Growing hydroponics as an alternative for growing plants that do not need much space. And the yield, quality and quantity sufficient for the needs of the market. By cropping hydroponics it. The solution requires a nutrient needs of plants instead of soil. But if used in excessive amounts. Will result in a buildup of nitrates in plants. Which is harmful to consumers
about the science project comparing the effectiveness of biological nutrient solution of chicken manure. Brown water Soy and compost on the growth of green oak grown in NFT technique aimed to compare the efficacy of a biological nutrient solution of chicken manure. Brown water Soy and compost on the growth of green oak, grown with the technique. The study found that the effective solution of biological Brown water effect on growth, growth of the Green Oak planted by technical NFT best with an average weight of the Green Oak increased as 67.54 grams. the major source of fertilizer and manure. The average weight of the Green Oak increased as 58.90 grams and fertilizer from fermented soy can help green oak trees grow. Although the solution of biological Brown water effect on growth, growth of the Green Oak planted by technical NFT best, but it also has an average lower than the Green Oak planted with a solution of inorganic. or fertilizer AB, which has an average weight of the Green oak increased to 82.60 grams.
