Term
how to get certified 
Definition

1. find a suitable certifier (3rd party; st. dept. of ag., or private entity accredited by NOP)

2. submit application to certifier (info includes: type of operation, history of substances applied to land for previous 3 years, organic products being grown, raised or processed, organic system plan - OSP - describes practices and substances used in production)

3. completeness review: certifier reviews organic plan application to insure it complies with NOP natl standards

4. on-site inspection: a qualified inspector conducts an on-site inspection of the applicants operation

5. final review: if applicant has complied, the certifying agent issues a certificate 

Term
Important factors in certification

Term
living plants consist of:
Definition

70% water (7-95)

27% organic matter

3% mineral content

Term
soil groups
Definition

1 = sandy soil (low nutrient holding capacity)

2 = loamy soils and light clays

3 = fine textured, clayey soils and soils high in organic matter

4 = fine textured clayey soils of the AL black belt region (very high nutrient holding capacity)

Term
soil pH
Definition

*>7 = alkaline

*5.8-6.5 = slightly acidic, ideal for most crops

*5-5.7 = very acidic; ideal for acid loving plants (strawberries, radish, sweet potatoes)

*<5 = strongly acidic; lime recommended for all crops except blueberries

*most soils: 4.4 - 7.8

Term
Nutrient rating (depends on soil group or crop to be grown)
Definition

*VL: very low; fertilization needed; crop yield <50%

*L: low; fertilization needed; crop yield 50-75%

*M: medium; some fertilization required; crop yield = 75-100% of potential

*H: high; adequate for crop growth

*VH: very high; no nutrient needed

*EH: extremely high; excessive nutrient level could damage crop

Term
five horizons of a soil profile
Definition

1. Organic or “o” horizon – leaf litter and other organic matter on the surface

2. Topsoil or “a” horizon – organic matter, roots, bacteria, fungi, small animals (where we are trying to develop organic matter; must get fertilizer into this layer for root development)

3. Subsoil or “b” horizon – low in organic matter; zone of accumulation of leached materials

4. Transition or “c” horizon

5. Final horizon or “r” or un-weathered bedrock (parent material)

Term
ideal composition of soil
Definition
air = 25%; mineral particles = 45%; water = 25%; organisms = 10%; roots = 10%; hummus = 80%; organic matter = 5%
Term
compacted soils (zones)
Definition

-Probing the soil with a knife or pencil will help show areas of compaction

-They tend to have large clods with don’t break up easily

-Absence of vertical cracks

-Shallow rooting

 

Term
clods
Definition

-Large clods with smooth surfaces indicate poor structure

-Small clods with irregular surfaces (soil crumbles) indicate good structure

-No consolidation into clods (crumbs) indicate poor structure

Term
cracks
Definition

-Contain air for roots and soil organisms; allow drainage and provide channels for new root growth

-Presence of horizontal cracks along with a lack of vertical cracks are an indication of compaction 

Term
biological activity
Definition

-Poor structure inhibits biological activity

-Numerous earthworms and their channels, other soil life and rapid decomposition of crop residue are an indication of few structural problems

-Silty loam: moulds easily; silky feel; sticks together

-Clay loam: binds strongly into a ball; forms a polish when smeared between fingers; is sticky

-Clay: binds into a strong ball that is difficult to deform; forms a high polish when smeared between fingers
