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.
The Shantung Maple ( Acer truncatum ) is also known as the Purple Blow Maple due to the color of its newly emerging leaves which are red-purple (see photo below). These young expanding red-purple leaves change to green as they mature. Leaves are small, about the size of Japanese Red Maple leaves, perhaps 3’-4’ wide at maturity. The Shantung Maple grows 1′-2′ annually reaching 25″ tall and wide. This is our tree for all planting situations. This Maple does well in heavy clay, sandy soils, full sun, or part shade. It can be planted in a lawn or next to a hot asphalt street (see photo below). It seemingly is a happy tree enjoying life wherever it is placed. One place we would not recommend planting this tree is in a rockscape which is just too hot and inhospitable to support this beautiful tree. A smaller tree, the Shantung Ma...
