Loss of organic material<br />

in the soil<br />

A theoretical estimation to give an idea of the yearly loss organic material.<br />

Principles<br />

• Cultivated topsoil: 25 cm (0,25 m)<br />

• Surface: 10.000 m 2<br />

• Organic matter: 2%<br />

• Specific gravity soil: 1.300 kg / m 3<br />

• Mineralisation factor: 3% year<br />

• Organic matter FERTIPLUS ® 65%<br />

Cultivated soil<br />

• 0,25 m x 10.000 m 2 x 1.300 kg / m 3 = 3.250.000 kg<br />

• Total organic matter in soil: 3.250.000 x 2% = 65.000 kg<br />

Yearly breakdown of organic matter<br />

• 65.000 kg x 3% = 1.950 kg<br />

Conclusion<br />

Although Organic Fertilizer is not only a substitute of organic<br />

material it can clearly be used for that. Organic Fertilizer<br />

should be used on base of crop needs in basic Fertilizer and<br />

organic matter replacement in your field.<br />

Most important<br />

parameter on soil fertility<br />

is organic matter<br />

Replacement of organic matter<br />

• Crop rests in the field: 750 - 1.250 kg<br />

• Netto need of external organic material:<br />

700 - 1.200 kg<br />

• In terms of Organic Fertilizer 4-3-3 65 OM:<br />

1.100 - 1.850 kg<br />
