Our nutrient feeder range are primarily crop specific and contain the key nutrients for a range of crops.
The more general feeders include Croplifter, Nutribooster, N36 and Stretchur N.
Croplifter and Nutribooster are N,P,K macronutrient providers, with additional biostimulant amino acids. They are applied regularly, ensuring there is no nutrient shortage during periods of stress or rapid growth.
Stretchur N is both environmentally and economically beneficial, as the Nitrogen Utilisation Efficienc (NUE) is greater than 90% – significantly in excess of fertiliser N.
We also offer Precision Feeds – a tailor-made soluble powder to match a crop requirement, as identified by a leaf or petiole tissue analysis. This service is very targeted and minimises delays to ensure the Precision Feed is quickly applied.
Fielder’s “Specialist Feeder” range
Stretchur N


We have recently developed Stretchur N, a slow release foliar nitrogen that is both good for your crop and the environment. The phased release source of nitrogen is used to replace some of the seedbed or top dressed fertiliser nitrogen, as well as providing a boost for high yielding crops. Of particular benefit to cereals, rape and maize.
We can proudly say Stretchur N will reduce your carbon footprint (when compared to more traditional N products) through NUE’s that break down N in phased stages. Furthermore, independent trials have shown Stretchur N increases fresh weight by up to 13%. Lastly, it can save you cash as low application rates are needed compared to foliar ureas.
Since its launch in 2019 this has been one of our most successful products.
28% N
Stretchur N is sold as a liquid in 20L containers.
CropLifter


CropLifter is a superior foliar feed for application to a wide range of crops during periods of rapid growth or stress. We have blended an outstanding ratio of N:P:K, helping the crop achieve a perfectly balanced level of nutrition. We believe CropLifter gives your crop all the vital trace elements it needs.

Maize Feeder

Maize Feeder is an effective and blended mix of all the major nutrients. Our studies have shown these nutrients are essential for the early growth and development of maize plants. Formulated with humates, plant uptake is improved. Translocation also occurs more effectively to sites of active growth.
2.3% N, 8.8% P, 2% K, 3.3% Mg, 1% Mn, 1% Cu, 1% Zn, 4.5% SO3

Embrace

Embrace is a liquid mix of essential plant nutrients. We have also added an amino acid complex. Consequently, this assists in all plant metabolic processes, which are especially beneficial during periods of rapid growth. Embrace has been specially formulated to treat oil seed rape and brassica.
Benefits of this product include its ability to be quickly absorbed by the crop; it is a stable liquid, rather than a suspension; and it is an easy and safe product to use.
7.5% N, 7% B, 3.9% S, 2% Mg, 0.2% Mo + amino acids
Embrace is sold as a liquid in 10L containers.
Potato and Crop Feeder

Potato and Crop Feeder is sold as a liquid in 10L containers.
N36

N36 is a concentrated foliar source of nitrogen and, like many of our nutrient feeder products, can be applied repeatedly to maintain green leaf area in a wide range of crops. Feeder N36 can also be used to encourage crops to recover from stress.
36% N + traces
Organic Feed

Organic Feed is proudly approved for use by OF&G. This product is a true solution of N,P and K, for organic growers whose soil may be lacking nutrient availability and thus require a foliar nutrient boost to their crops. We have also included amino acid biostimulants in this product.
10% N, 9.75% P, 9% K + 1% amino acids + traces
Organic Feed is sold as a liquid in 10L containers.
Nutribooster

Nutribooster is a balanced NPK foliar fertiliser, with an additional range of chelated micronutrients.
It is formulated with stickers, surfactants and humates. All of which prevent or eliminate nutrient deficiencies in a wide range of crops. Nutribooster also improves leaf colour and shine of ornamentals.
We recommend Nutribooster to be used on agricultural, horticultural and fruit crops, as well as professional turf and amenity grasses.
9% N, 9% P, 7.5% K + traces
Nutribooster is sold as a liquid in 10L containers.
Precision Feeds

Precision Feeds are our purpose made soluble powders. They are specifically formulated to match a crop requirement as identified by leaf or petiole tissue analysis. On receipt of the analysis results, we tailor-make a balanced nutrient mix and advise on application rates and timings. We apply this info onto a label on the bag and despatch direct to the grower for immediate use, minimising any delays in rectifying the deficiency.
