Nitrosol-Biological Fertlisers

Bulk blood and bone fertilisers in an easy to use liquid form, shipped across New Zealand

Nitrosol - What is it?

Nitrosol is a well-known and well-respected liquid blood and bone fertiliser.  The traditional bulk blood and bone in an easy-to-use concentrated liquid.  Nitrosol blood and bone fertliser is sourced from sheep (ovine blood and bone) sourced from New Zealand sheep processing abattoirs.

Nitrosol is formulated as a total replacement, one-step fertiliser containing:

  • A balanced supply of the major nutrients with being NPK 11.5.7 - feeding through BOTH the foliage and roots (via the soil) Nitrosol is readily available for the plant to use.
  • Apart from being high in organic matter Nitrosol blood and bone includes amino acids, albumin, globulin, cholesterol, humates. and protein; the building blocks of life.
  • Two naturally occurring growth promoters are included in the formulation to boost and sustain plant growth and health.
  • The Nitrosol liquid biological fertiliser is formulate to give the perfect mix of essential trace elements and minerals.

Nitrosol is a Balanced Fertiliser

The real key here is balance. Most scientists recognise that a balance of all elements in the soil is absolutely crucial to obtain healthy plant growth.

There is no point in just applying large quantities of just one or two elements.  This can have the effect of 'locking-up' many important trace elements or minerals.

For example bulk K (potassium) can cause magnesium to be unavailable and magnesium can be important for good animal health.  Too much P (phosphorous) can 'lock-up' trace minerals such as iron, calcium, copper and zine.

The original Nitrosol formula, was developed more than 30 years ago by the late Dr. G. P. Kauzal, a highly respected Australian vet scientist, has had years of research and practical testing, resulting in a totally balanced Nitrosol NZ fertiliser.

Nitrosol is not just a blood & bone fertliser but a blend of blood and bone and numerous other ingredients resulting in this 11.5.7 NPK concentrated liquid fertiliser.  Two of the ingredients are naturally occurring growth promoters.  One being a powerful stimulant derived from selected plant foliage and waxes.  This helps the plants to absorb and utilise the nutrients in Nitrosol natural fertiliser but also those nutrients in the soil.

Photosynthesis is stimulated within minutes of the application of Nitrosol.  This promotant also boost the plants natural sugars which for pasture and animal feed crops improves the palatability and taste for stock.  These increased sugar levels also mean an increase in the levels of all the micronutrients, vitamins, trace minerals and elements and energy needed for animal vitality and good health.

The second natural growth promoter is responsible for cell division and elongation.  Together the two aid promotants help the plant to absorb and use all the available nutrients in the soil plus those nutrients in the Nitrosol liquid NPK fertiliser itself.

Nitrosol Benefits

Farmers, horticulturalists and viticulturists are constantly demanding fertilisers that perform, which begs the question - how can I truly benefit from using Nitrosol liquid NPK blood and bone fertiliser?

Nitrosol NPK is proven to produce great results both in New Zealand but also around the world.  Whether you are involved in pastoral farming, horticulture, cropping, recreational turf and sports ground, nurseries or even just for your home or lifestyle block vegetable or flower garden you can expect:

  • A more friable and aerated soil structure which as well as holding more moisture for the plant will also drain better.
  • Improved productivity, health, and quality.
  • Healthy robust plants which provide higher yields but also healthy plants become more resistant to attack from insect pests and diseases.
  • Improved plant recovery after stressful situation like adverse weather or transplanting.
  • A general improvement in stock health which can result in lower animal health costs, improved productivity and therefore increased profits.
  • Improvements in dry matter yields and quicker breakdown of thatch and dead plant material from the increased microbial activity in the soil.
  • Improved palatability and nutrient values of grazing pasture die to increased metabolisable energy.
  • More organic activity in soil leads to an increase in earthworm numbers and beneficial soil organisms.
  • Reduced groundwater contamination, runoff or leeching as a result of Nitrosol's organic nature and the fact it is a suspension.
  • Ability to reduce or even eliminate the addition or nitrogen such as urea or sulphate of ammonium.

Nitrosol - Cost Efficiency

Nitrosol fertiliser is very cost efficient.  Partly because it is a liquid and is packed full of active ingredients. Nitrosol fertilisers only use the highest quality blood and bone with strict minimum quality levels. Once all the trace elements, minerals and growth promotants are thoroughly mixed, the Nitrosol mixture goes through a grinding mill and then through a fine screen to ensure that the largest particle size is 250 microns or 0.25mm.  This means Nitrosol blood and bone liquid concentrate can be sprayed through conventional spraying systems.

  • Being a concentrated liquid, Nitrosol is very cost efficient to transport and easy to use.
  • You can apply Nitrosol with normal ground or airborne spray equipment.  You can usually apply at the same time as your regular spray programme.
  • Nutrients are bioavailable which means the organic matter decomposes slowly and provides extended growth over a long period.
  • It can act as a sticker/spreader for herbicides, pesticides and fungicides. Farmers and growers have reported they often can use less chemical with the same or even better results.  Although compatible with most products just double check with your chemical supplier.

This fertilizer enhances plant nourishment, stimulates soil microbiological activity, and promotes nutrient cycling, along with boosting bacterial and fungal activity and earthworm populations. These benefits contribute to improved soil structure and greater availability of essential nutrients, trace elements, and minerals for plants.

Nitrosol MagSulphate

Nitrosol MagSulphate is a liquid supplement providing magnesium and sulfur to address plant deficiencies and support animal health. It contains 7.5% organic carbohydrates to nourish and stimulate biological activity in the soil.
