Calcium compost

 

Organic matter is an important aspect for every type of soil with regard to its fertility. Organic matter has an effect on:

  • Chemical bonding of minerals: because of its bonding capacity, organic matter is able to bond positively charged parts. This ability lessens washing away of potash, magnesium and calcium for example. 
  • Water balance: soils that contain a lot of organic matter are better able to retain water and are therefore less susceptible to drought during dry periods. 
  • Air balance: it is proven that with high levels of organic matter there is a better balance between air, solid parts and water.
  • Soil biology: organic matter is needed for soil ecology. Especially soil fungi and soil bacteria do well when there is enough organic matter available. 

Supply of organic matter through compost is one of the most effective ways. A year after application, 90% of organic matter is still present in the soil, while this is much less with other soil improvers. The organic matter remains stable due to the composting process. 
 
On clay soils the soil structure is dependent on the calcium deposits. Clay particles can also bind positive elements, similar to organic matter.  When insufficient calcium is bonded to the clay particles, the structure of the soil will be negatively affected. Scattering gypsum is proven to improve the level of calcium deposits in clay soils. This has a positive effect on the soil structure, bringing more air, improving manageability and decreasing soakage.

Features and advantages

 

Calcium compost is a mixture of certified laco-compost Class 1 and agricultural gypsum in the most optimal ratio of 3:1, making calcium compost a soil improver with a double effect on the soil structure of clay soil: both the organic matter in the compost as well as the gypsum have a positive effect on the soil and therefore on the growth of the crops. The compost and gypsum are homogeneously mixed and sifted, making it easy to scatter without pollution.

  • Application of organic matter and gypsum in one operation.
  • Calcium compost improves defences against weather influences.
  • This makes crops better resistant against periods of dry or wet weather.
  • Activation of soil ecology, making better use of nutrition present in the soil.
  • Applying extra organic matter through Calcium Compost improves the structure of the soil, the manageability and the air and water balance.
  • Result: A better soil fertility and a secure yield.

With 20 tonnes of Calcium Compost per ha (8 tonnes per acre) you apply:

  • Effective organic matter: 2980 kg, in comparison this is 100% green manure 850 kg.
  • Sulphur (SO3): 2000kg, completely available during the first year.
  • Calcium oxide (CaO): 1250 kg, completely available during the first year.
  • Lime (Nw or ZBW): 225 kg, this is comparable to 409 kg lime with 55% Nw.
  • Nitrogen (N): 122kg, of which 16 kg are released the first year, the rest over a period of 10 years.
  • Phosphate (P2O5): 58 kg, of which 35 kg are released the first year, the rest over a period of 10 years.
  • Potassium (K2O): 102 kg, of which everything is released the first year.
  • Magnesium (MgO): 62 kg, of which 15 kg is released the first year, the rest over a period of 10 years.
  • Mineral nutrients: Boron, Copper, Manganese, Zink, Sulphur, Cobalt, Sodium.

* EOS = Effective organic matter: the quantity of organic matter still present in the soil after 1 year.
* Total supply and availability of Calcium Compost the first year is: N: 15%, P2O5: 75%, K2O: 100%, MgO: 30%.


Practically every farm has room for Calcium Compost!

  • Per tonne, Calcium Compost contains 6.1 kg N and ca 2.9 kg P205.
  • Nitrogen counts for 10% (at 20 tonnes per ha, ca 12 kg)
  • Phosphate counts for 50% (at 20 tonnes per ha, ca 29kg)
  • Calcium Compost can be used year round and usually meets Skal requirements.

 

Advice

 

  • Calcium Compost is very well suited for use in spring or autumn.
  • The recommended dose for repairs is 25-30 tonnes per ha (10- 12 tonnes per acre)
  • Repeat once every 3-4 years with a maintenance dose of 15 tonnes/ha (6 tonnes per acre)
  • Supply is available throughout the year, but order well in advance so we can produce in charges.

 

Fertilizer Act

  • The phosphate quota for farmland varies between 65 and 85 kg P205 per ha per year, depending on the Pw.
  • This phosphate quota applies to Calcium Compost, compost, manure, betacal and artificial fertilizer.
