Calcium Magnesium Sulfur
Helps translocation of carbohydrates Essential to healthy cell walls Aids in development of root structures Calcium is active element in lime and gypsum which are used to treat saline and/or alkali soils.
Growing point of plant (terminal bud) dies under severe deficiency Margins of leaves (usually younger ones) have a scalloped appearance, remaining foliage is abnormally dark green Plant shedding blossoms and buds prematurely Stem structure weekend
Essential ingredient of chlorophyll Deficiency Symptoms: Leaves are abnormally thin and brittle Curve upward With acute deficiency leaves may dry up and die On trees twigs are weak, subject to fungus infection, drop leaves prematurely Leaves loose their color at the tips and between veins Starts with lower leaves and moves upwards
Component of cystine, a constituent of protein Aids in the synthesis of oils Deficiency symptoms: Lower leaves yellowish green Stems are small in diameter and hard and woody Although roots are well developed, they are also small in diameter
Breaks compaction from tillage, wheel traffic, or animals Aids in water penetration of soil profile Eliminates impermeable layers in soils Should be done when soil is dry for “shattering” effect Generally 24”-36” deep
Breaks large clods from subsoiler Incorporates residue and eliminates weed growth Commonly 6” in depth
Important to incorporate phosphorus and potassium at this stage Nitrogen assists in breakdown of heavy crop residue Apply soil amendments based on soil tests so soil can sustain a healthy crop from the start
Incorporates all organic matter and residue on surface 180 degree inversion of soil Generally 10-12” in depth Aerates the soil Can provide weed and disease control Incorporates fertilizer and soil amendments deeply Can be accomplished on moist or dry soil, but not wet!
Typically with a cultipacker or spiketooth harrow hooked behind the disk Breaks down large clods from plowing Begins firming process of seedbed Kills weeds and vegetative growth Generally 6” depth
Cuts off high spots and fills depressions Smoothes but does not level Should be done with dry, residue free soil surface
Borders are installed for flood irrigation to guide/control even flow of water across field Generally 18-24” in height (factor 1/3 shrinkage) Length and width of borders depends on: Equipment width Soil type Water supply
Accomplished via flood or sprinkler irrigation Addition of water through effective rooting depth of crop Germination of weeds and volunteer Testing of leveling operations Prepares moist firm seedbed Once weeds have germinated and soil is dry enough to safely enter field with equipment (7 or more days), field is disked again and then planted
