Backyard Basics SOIL PREPARATION An Earth Kind Method

Backyard Basics SOIL PREPARATION ~ An Earth. Kind Method ~

PURPOSE OF THIS PRESENTATION IS: n n To present the concept of “Backyard Basics” To create an awareness of improving soils for: n n n Backyard vegetable production Backyard fruit production Backyard herb production Increase beneficial soil microbes Reduce the need for fertilizers Reduce the need for pesticides

Soil Content Outline n Ideal Soil n n Organic matter content Soil organisms n n n Air Minerals/Nutrients n n Micro & Macro Primary, secondary & micro-nutrients Salts

The Ideal Soil Contains: n n n 1% Micro/Macro Organisms 5% Organic Matter 45% Minerals 25% Air 25% Water 0% Salt

Organic Matter Compost - Everything that was once living. n n n Tree leaves Grass clipping Kitchen scraps Old plants - flowers, herbs, and vegetables And lots of other stuff. . . + Manure & water

Soil Micro/Macro-organisms All the critters that are still living include: n Micro-organisms: n n Bacteria, fungi, yeast, nematodes, algae, etc. Macro-organisms: n Earthworms, sow & pill bugs, snails and slugs, earwigs, millipedes & centipedes, fire ants, termites, springtails and snakes.

Air The soil’s most plentiful component! n Oxygen - about 45% n Carbon - about 44% n Hydrogen - about 6%

Ideal Mineral Amounts Too little causes deficiencies, Too much causes toxicities & ties up other minerals n Primary Nutrients n n Secondary Nutrients n n Calcium - 6. 5 %, 650 ppm Magnesium -0. 3% Sulfur - 0. 5% Micronutrients n n Nitrogen - 2 -4 % Phosphates - 0. 5% Potassium -11. 1% Iron - 50 -400 ppm Zinc - 15 -50 ppm Manganese - 20 -200 ppm Salts (sodium & chloride) - hopefully none

Total Salts What’s Good & What’s Not! n n Low Salinity Hazard = < 160 ppm Medium Salinity Hazard = 161 -480 ppm High Salinity Hazard = 481 -1440 ppm Very High Salinity Hazard = > 1440 ppm

Garden Location Outline n n Sunshine Drainage Competition Garden size

LOCATING THE GARDEN The First Step: n Sunshine n n n Full sun (>6 hours per day for flowers & fruits) Partial sun (4 -6 hours per day) Shade (4 hours or less for leafy plants)

LOCATING THE GARDEN The Second Step: n Drainage n Do a “perk” test. Total drainage in 24 hours or less is good, greater than 24 is bad and a raised bed is a must.

LOCATING THE GARDEN The Third Step: n Competition n n Weeds - Avoid areas of the landscape that contain hard to manage, noxious weeds. Use: Solarization, heavy mulches, or cover crops. Tree and Shrub roots under the garden will grow upward in search of water and nutrients. Use: Weed barriers that are permeable to air and water.

n Solarization Process n n n n Go t P rob lem s? Till to break up clods Add organic matter Dampen for heat buildup and retention Spread a 4 -6 mil clear plastic sheet Bury sides Let stand for 6 -8 weeks. Heats to 140 degrees F. at the surface and up to 110 at 12 inch soil depth Kills soil micro and macroorganisms in the top 6 in. of soil

LOCATING THE GARDEN The Fourth Step: n Garden Size n n n 400 sq. ft. - the recommended size for a family of four. Takes 1 hour of maintenance per day 7 days per week

PREPARING THE GARDEN The First Step: n Single till or double till the entire plot to 4 -8 inches.

PREPARING THE GARDEN The Second Step: n n For raised beds add sandy loam soil to a depth of 4 -6 inches For in-ground beds add 2 -4 inches & till

PREPARING THE GARDEN The Second Step: n Check the p. H n n Add lime to increase the p. H Add sulfur or peat to decrease the p. H Fort Bend County

What is p. H? n n p. H is the potential of the hydrogen ion The logarithm of the reciprocal of the hydrogen-ion concentration in gram atoms per liter. The balance of hydrogen (H+) and hydroxyl (OH-) ions and is therefore p. H neutral (p. H 7) A measure of the acidity or alkalinity of a solution on a scale of 0 -14 (where 7 is neutral)

What does all that mean? n You ain’t got no business messin with what you can’t understand. So i Repo l rt

Special Considerations When Changing p. H Consider: n Organic matter source and content n Acid rain n Soil temperature n Buffering capacity

p. H Effects on Nutrient Availability

PREPARING THE GARDEN The Third Step: n Amending the Soil n n Add well rotted compost - the more the better. Add aged manure – add 1 -2 inches per year.

PREPARING THE GARDEN The Fourth Step: n Amending the Soil With Additional Nutrients n n Adding man-made nutrients Adding organic fertilizers

Adding Fertilizer n n n Don’t guess – Soil Test! Test the root zone Take 10 plugs and mix well for one composite Use clean tools and a clean bucket Submit with $$ 4 weeks prior to planting

Ask Your County Agent n Tell him/her: n n n Soil type Moisture supply What the crop is Whether or not organic matter is used And, previous fertilizer used and when

Recommended Plant Nutrients n Primary Nutrients: n n Secondary Nutrients: n n Calcium - 6. 5 %, 650 ppm, Magnesium -0. 3%, Sulfur - 0. 5%, Micronutrients: n n Nitrogen - 2 -4 % , Phosphates - 0. 5%, Potassium -11. 1%, Iron - 50 -400 ppm, Zinc - 15 -50 ppm Manganese - 20 -200 ppm Trace n n Molybdenum Salts (sodium & chloride) -hopefully none

FAQ’s Regarding Fertilizers Why should I fertilize my landscape/garden? What do I need know about my landscape (soil type, plant type, exposure, water source) ? What do I need to know about fertilizers? How do I choose a fertilizer? How much fertilizer should be applied? When should I fertilize? How often should fertilizer be applied? What is this I hear about environmental issues and fertilizer application

PREPARING THE GARDEN Amending with “man-made” Nutrients n Complete & balanced fertilizers (all-purpose fertilizers) n n Complete fertilizer & unbalanced fertilizer n n (1: 1: 1 ratio): 8 -8 -8, 10 -10 -10, 13 -13 -13, 20 -20 -20 (1: 2: 1 ratio): 12 -24 -12, 10 -20 -10, 10 -5 -10, 6 -12 -6, (3: 1: 2 ratio) 15 -5 -10, 21 -7 -14, 18 -6 -12 (4: 1: 2 ratio) 16 -4 -8, 20 -5 -10 Incomplete fertilizers n 21 -0 -0, 33 -0 -0, 45 -0 -0, 0 -20 -0, 0 -0 -60

What Does the Numbers Mean? n n n The numbers on the bag are important! These numbers are referred to as the “grade” or minimum guaranteed analysis The numbers in order represent the N: P: K ratio n n n Nitrogen % by weight Phosphate (P 2 O 5) % by weight Potash (K 2 O) % by weight

Q. How do I know what nitrogen products are in the bag? A. Look at the other information on the bag! • It will tell you the sources of N in the container. • If slow release N sources are in the bag they will be listed. Slow release sources will cost more than readily available N sources.

Difference Between a Slow-Release and a Fast-Release Fertilizer Lasts 6 weeks Fast-Release fertilizers are water soluble thus are dependent on rainfall. Slow-Release fertilizers are Lasts 10 weeks water insoluble. They are broken down and released by microbial activity.

What Does the Numbers Mean? n The fertilizer below contains some nitrogen that is listed as water insoluble or "WIN" (slow release N). The percentage is listed at 3. 6%. It is also stated on a weight basis. Therefore, 3. 6 divided by 12 is 0. 3 or 30%. The other 70% is considered readily available nitrogen. 70% Readily available N Slowly available N 30%

Comparing Nitrogen Sources in Lawn Fertilizer Nitrogen Source Category CHARACTERISTIC SLOWLY AVAILABLE READILY AVAILABLE Response time Slow Quick Burn potential Low High Application frequency More seldom More frequent Water solubility Low High Residual effect Variable Short Cost of product High Low Leaching potential Lower High Surface runoff Reduced potential Higher potential Environment friendly Yes no
