Many countries are now confronting an economic and food crisis. Increased development in the agricultural sector is needed. During an economic crisis period, one of the main sources of a country’s income is the agricultural sector, so clearly increasing crop yield is necessary. One main factor that has to be considered here is soil fertility.

In many countries, the quality of the soil has deteriorated because of growing crops continuously for more than 10 years. Applying fertilizer is the way to increase crop yield and enhance soil fertility. Farmers usually apply chemical fertilizer, e.g. 46-0-0, 15-15-15, etc. While research shows that almost all kinds of plants need only 1.5% N (nitrogen), only 0.5% percent P (Phosphorus), and only 1% K (Potassium), farmers commonly over dose the soil with fertilizer, and thereby cause an accumulation of chemical residue in the soil. The soil then coagulates with the result that plant absorption of the nutrients from the soil gradually decreases.

Most farmers realize that the negative impacts of fertilizer application include not only soil deterioration, but also yield decrease. Governments then formulate the policy to promote the production of poison-free agricultural products, as well as environmental management for sustainable agriculture. Artemis & Angel Co.; Ltd. recognizes the importance of this issue, and has produced and distributed bio-products in line with such government policy. The products help to decrease costs and increase crop yield. see further at
