Earth-Kind® Vegetables and Herbs

Tim Hartmann Program Specialist

Texas A&M AgriLife Extension

Goals of Earth-Kind

1. Conservation of water AND quality

2. Reduction of chemical and fertilizer use

3. Energy conservation

4. Reduction of solid waste

Seven principles of Earth-Kind:

1) Planning and design

2) Soil analysis and preparation

3) Practical turf areas

4) Appropriate plant selection

5) Efficient irrigation and rainwater harvesting

6) Effective use of mulches

7) Appropriate maintenance

Why Grow Vegetables

Grow your own food

High quality, fresh produce

Concern over chemical use

Save money

Recreational value

Ideal soil type??? Meanwhile in Norththeast Texas….

Soil Preparation ∗ Disking, spading hard / compacted soil

∗ Incorporation of > 3” of finished compost

∗ Fully-composted materials (especially for manure)

∗ Drainage through creation of structure

∗ Water / nutrient retention

∗ Slow-release source of nutrients

∗ Soil microbial populations

∗ Raised planting beds in heavy soils

∗ Addition of nutrients, ONLY if necessary!!!

∗ Maintain 1 to 2 inch layer of mulch http://www.cranfordinc.com/

Not all composts are created equally…..

Soil Testing

∗ First step in preparing for planting

∗ Identifies problems / deficiencies

∗ Basis for accurate fertility management

Fertilizing Vegetables ∗ Based on soil tests

∗ Smaller applications

∗ Organic fertilizers

∗ Less concentrated

∗ Slower-release time

∗ Typically several nutrients

∗ Synthetic Fertilizers

∗ More concentrated (burning)

∗ Granular (quick- and slow-release)

∗ Liquid / water-soluble

Common Vegetable Pests

Know the Good Guys

Integrated Pest Management

∗ Provide plants with the best care and culture possible.

∗ Use only the most adapted varieties.
