Application of Liquid Fertilizer Recommendations Nozzles and Accessories Catalogue LF 2014

Lechler agricultural spray nozzles – for your success and for the good of the environment Systems for the application of LF should account for the requirements of the crops/plants, the economy and the ecology. These systems should guarantee an even and precise distribution and a preservation of the crop. In combination with the application of pesticides the selected nozzle technology should be in line with the instructions of the pesticides. This brochure would like to give some advices and guide lines for a successful application of LF. The requirements to the sprayer technology and the nozzles...

Benefits of Liquid Fertilizer Economical advantages when used in combination with pesticides The nitrogen price of LF is very often lower compared to the granulated fertilizer. The application of LF in combination with pesticides reduces additionally the operational costs. On average the price of LF has been 15 % below the granulate option. In addition the operational application costs can be reduced by 2.5 – 3 Euro per hectare with combined application and savings in transport and handling. Accurate and even distribution of LF with increased output Flat fan or special fertilizer nozzles from...

Constitution and characteristics of LF variances UAN (urea-ammonium nitrate) UAN (liquid urea-ammonium nitrate) is the most popular type of LF. Pure UAN includes 28 % N by weight nitrogen. 50 % of the nitrogen is amide (+NH2), app. 25 % is ammonium (NH4+) and the other quarter is nitrate (NO3-). LF with premium quality should possess a high surface tension, a neutral pH value and a level of Biuret below 0.2 – 0.3 %. Amide nitrogen is available for the crop 1 – 2 days after application. The ammonium and nitrate components can be absorbed by the leaves and roots directly after the application....

Application of LF in a future orientated agriculture Guest comment of Mr. Fuchs, SKW, LF application research department The demands of the worldwide markets force the farms to optimize the special intensity, means also lowering costs. One opportunity is the substitution of granulated fertilizer by liquid variances. The advantages are not only based on the cheaper nitrogen price. LF includes further positive characteristics which contribute to a positive result. One characteristic is the same but mostly higher efficiency of LF compared to granulate. But in practice there is still uncertainty...

This means also to utilize full virility of fertilizer and to rescue the fertility of the soil. LF is an excellent tool especially due to precise calibration and application. As there is no significant difference between the fertilizers variances it is not the most important question which N fertilizer should be applied. Much more important is to follow up the different application guide lines and to work on the conditions of best practice. LF and precision farming Spreaders for granulate and sprayers for LF are able to apply on partial areas in the field. Sprayers are equipped with valves which...

BBCH growth stage In winter grain LF can be applied during the dormancy period onto the frozen crop, the rate can be 60 – 100 kg N/ha. The crop should have min. 3 – 4 leaves and should posses an excellent strong root system. Further combinations of LF are possible with growth regulators. If the run to seed has started, the max. rate of LF in combination with pesticides should be max. 50 l/ha LF, den- sity 1.28 kg/m3. The relation water : LF should be...

Fertilizer application of blossom max. 50 l/ha UAN + water + pesticide hose drop 1.0 – 10.0 bar* * avoid direct contact with crop BBCH growth stage In winter rape can be applied in total 200 kg N/ha, spitted into 2 applications during the vegetation period. This can be done by nozzles or hose/tube drop systems. Nozzle guide at the start of germination 220 – 350 l/ha: n FD 04 to 10 n FL grey with Dosing orifices 1.5/1.8 n ID3 120-04 to -08 n IDK 120-05 to -06 2nd N-application until generation of buds 170 –...

Nozzle recommendation in corn Copyright © 2013 Lechler GmbH. All rights reserved. BBCH growth stage Corn is very sensitive to the application of LF directly onto the leaves. An application before germination in combination with herbicides is no problem. The addition of a dinitrification inhibitor is recommended. Later applications directly into the crop should be done by DroplegUL or hose/tube drop systems. Nozzle guide before seeding until 3 days afterwards 280 – 500 l/ha LF: n FD 04 to 15 n ID3 120-04 to -08 n IDK 120-05 to -06 Combined application of LF + pesticides (before germination) 200...
