Definition
|
|
Term
| why you want the ratios of nutrients to be correct |
|
Definition
| so you don't throw off the internal chemistry of the plant |
|
|
Term
| why roots go deeper in less acidic soils |
|
Definition
| because more acidic soils have too much aluminum |
|
|
Term

Term
|
Definition
| basically means resistant to management or athority |
|
|
