In the red column are the nutrients called Anion, which have a negative charge opposite of the Cation nutrients. The soil has a negative charge of various strengths called the CEC or Cation Exchange Capacity. For example sand has a weaker CEC than clay therefore clay can hold more Cation nutrients than sand. However the negative charge of soil will repel the nutrients that already have a negative charge, the Anions in the soil therefore cannot hold onto those nutrients. TerraPro however can hold both Cations and Anions by having the Mechanism of Action of a Chelation Overlay.
Goatheads ( Tribulus terrestris ) are native to Southern Europe, Asia, Africa and Australia. Goatheads are also called stickers, sticker weed, bullhead, devil’s weed, and puncturevine. Goatheads are easily recognized by their prostrate growth form, leaves with leaflets, yellow flowers, and stickers (Goatheads). If you miss’em visually then they will stab you painfully in the fingers as you work your garden, or stick to your clothing and shoes. Goatheads are the primary reason local bicyclists must get “thorn proof” tires for riding on area trails and streets. Goatheads have prostrate stems that radiate outward from one central point. Leaves are compound with smaller leaflets. Lemon yellow flowers form along the stems and fertilized flowers form fruits. Fruits consist of several attached structures called nutlets (Goatheads). Each nutlet is a single seed that becomes hard or woody when mature. Each seed has two sharp spines that easily penetrat
