The arrowroot plant is native to the tropics of South America. It has a long history of cultivation by native peoples, who developed an extensive treatment process for extracting the usable powder from the roots. The roots are washed, scraped, beaten, soaked, pulped, and finally forced through a sieve.
A 100 pound bag of 16-4-8 contains 16 pounds of nitrogen, 4 pounds of phosphorus and 8 pounds of potassium. The rest if filler and minor elements. Even though it may cost more, a fertilizer containing slow release nitrogen is more efficient and cost effective in our sandy soils.ounding this number to six, you would apply six pounds of 16-4-8 fertilizer per 1000 square feet of lawn area. Using 12-4-8 fertilizer, you would apply eight pounds per 1000 square feet.
For example, a common type of all-purpose fertilizer is often referred to as 10-10-10. If you purchase a 50 pound bag, 5 pounds (or 10 percent) would be nitrogen, 5 pounds would be phosphorous and 5 pounds are potassium.r you can use granular organic fertilizers. Theyâre made up of grains such as ground corn, alfalfa, cottonseed or soy as well as blood and feather meal. The primary advantage of organic fertilizers is their slow release of nitrogen and other fertilizer elements. That means a lower chance of leeching or burning.
