Soil fertility for the garden

A. Soil Fertility

1. Nutrient cycles in general
2. Elements that plants need
3. Basics of soil - plant relationships
4. Data interpretation laboratory soil analysis results

B. Land Management for the Landscape

1. Tillage
2. fertilization
3. calcification
4. Processing of organic soil

C. Basics of soil and plant relationships

Phenomena underlying the association Soil and Crop

1. Ion exchange in the soil (anions and cations)
2. Soil solution and the mechanism of ion movement into the root
3. Factors affecting the uptake of nutrients
4. Conception of nutrient mobility

1 . Nutrients in the soil come from :

1. Primary mineral weathering
2. Decomposition of Organic Materials
3. Atmospheric
4. Fertilizers
5. Seep from other areas

2 . Nutrients availability to plants is influenced by :    

1.  pH
2. Potential Redok
3. Mineral Primer
4. Organic Materials
5. Seep from other areas
6. Temperature

3 . The movement of ions to the root

1. Interception
2. Mass flow
3. Diffusion

4 . Factors affecting the uptake of nutrients

1. The concentration of O2 in the soil
2. Soil moisture
3. Toxic substances ( toxins )
4. Temperature
5. Antagonism
6. Plant Health

5 . Factors that determine the mobility of nutrients :

1. Ion sorption by complex sorption
2. Ion deposition

Relative mobility

NO3 - , SO42 - --- > High Mobility

Na + > K + > Mg2 + > Ca2 +

Lyotropi series, easy or not ion exchanged

Li > Na > K > NH4 > Ca > Mg > Sr > Ba > H

6 . Elements that plants need

Macro elements : C , H , O , N , P , S - > Proteins + Compiler protoplasm

Micro elements : Ca , Mg , K , Fe , Mn , Mo , Cu , N , Zn , Cl , Na , Co , V , Si , Cn , H , O

- > Derived from CO2 + H2O
