Definitions

  • This invention relates to an agrochemical formulation for use as a fertiliser. Additionally, the invention relates to a method of fertilising plants, particularly crops such as cereals.
  • Microtrient fertilisers include nitrogen fertilisers, phosphate fertilisers and potassium fertilisers and fertilisers containing at least two of available nitrogen, phosphate and potassium.
  • Nitrogen fertiliser is in common use today. Common forms of nitrogen fertiliser include ammonium nitrate and urea. Ammonium nitrate is often used as a granular solid and is utilised inefficiently (around 45 to 50%) by most cereal crops. This presents three problems:
  • foliage fertilisers are however reported to have a series of disadvantages which impede their general use. If commercially available foliage fertiliser is used in the quantity necessary for plant nutrition, the leaves can be corroded or burnt, especially in dry, sunny locations of cultivation. To prevent these burns, the amount of nutrient must be reduced, so that fertilisation can be insufficient. The fertilisation must be repeated several times, which implies labour-intensive operation. Furthermore, the nutrients are often eroded from the leaves by wind or rain before they can be absorbed into the plant, so that they do not penetrate to the plant.
  • US-A-4576626 describes the use of various foliage fertilisers containing one or more macronutrients and, from 10 to 50% (by weight of total nutrients) of a natural or synthetic phospholipid selected from phosphatidyl choline, the hydrated phosphatidyl cholines, phosphatidyl ethanolamine, the N-acyl- phosphatidyl ethanolamines, phosphatidyl inositol, phosphatidyl serine, lysolecithin and phosphatidyl glycerol. All the indications in US-A-4576626 are that 10% is the minimum amount of phospholipid that can be used, irrespective of the nature of the phospholipid.
  • a method of fertilising plants comprising applying to plant foliage a macronutrient fertiliser and up to 5% by weight phospholipid (based on the total weight of the macronutrient(s) ) comprising lecithin.
  • a method of fertilising plants comprising applying to plant foliage a macronutrient fertiliser, a carboxylic acid or its salt and up to 5% by weight phospholipid (based on the total weight of the macronutrient(s) ) .
  • the plant may be a commercially valuable crop, such as one of the various grain crops, including wheat, winter . wheat, barley, oats and rye, or leafy crops such as brassica, including oil seed rape, and root crops such as sugar beet.
  • the macronutrient fertiliser may be a nitrogen , phosphate and/or potassium fertiliser.
  • a macronutrient fertiliser will generally be in liquid form (usually as an aqueous solution) and may be organic or inorganic .
  • Ammonium nitrate o ften conventionally applied as solid prills , is an example of an inorganic nitrogen-containing fertiliser and urea, often applied as a liquid spray, is an example of an organic nitrogen-containing fertil iser .
  • Other nitrogen fertilisers include ammonium sulphate, calcium ammonium nitrate, urea aldehyde condensates , magnesium nitride , ammonium nitrate/sulphate mixes , calcium nitrate and calcium cyanamide.
  • phosphate fertilisers are superphosphate, double superphosphate, triple superphosphate, ground basic slag, basic (Thomas) steel process phosphate, calcined phosphate , "rhenania phosphate” (phosphate product containing rhenanite) , dicalcium phosphate and rock phosphate.
  • micronutrient examples include sulphur, calcium carbonate, such as limestone or chalk; calcium oxide ; magnesium oxide; kieserite and dolomite.
  • Organic components may also be mixed in: guano , fish meal , bone meal , lignin or peat.
  • Trace elements i. e . micronutrients include manganese , z inc , iron and copper, e.g. zinc oxides, zinc sulphates, zinc carbonates, copper oxides, molybdenum sulphates and borates.
  • the carboxylic acid or salt thereof may be a lower carboxylic acid or salt thereof, such as containing from 2 to 9 carbon atoms.
  • a particularly preferred acid is propionic acid.
  • the acid may be applied either in its undissociated form or as a salt, particularly as an alkali metal salt (such as a sodium or potassium salt) or as an ammonium salt, which has the added effect of providing nitrogen. It will be appreciated that whether carboxylic acids are present as the free acid for a salt will depend on the pH of the environment. In the present specification, therefore, unless the context otherwise requires, references to a carboxylic acid are to be construed additionally as references to a salt thereof.
  • the amount of carboxylic acid which may be used may be up to 10% or more by weight (based on the total amount of macronutrient(s) ) . Typically it will be present at least in amount of 0.01% or even 0.1%. A range of 0.5% to 5% may be usual.
  • Phospholipids may in general be selected from phosphatidyl choline, the hydrated phosphatidyl cholines, phosphatidyl ethanolamine, the N-acyl- phosphatidyl ethanolamines, phosphatidyl inositol, phosphatidyl serine, lysolecithin and phosphatidyl giycerol.
  • Lecithin or phosphatidyl choline
  • the fatty chains of the diglyceride may be derived from a number of carboxylic acids, including C 15 -C 2 5 carboxylic acids, particularly C- j _g-C 2 2 carboxylic acids.
  • the lecithin may in fact be a mixture of different lecithins, as will usually be the case when the lecithin is extracted from natural sources.
  • the lecithin or other phospholipid may be hydroxylated or otherwise derivatised if desired.
  • lecithin be of plant origin or similar in compositions to lecithins of plant origin, particularly from soya beans. Soya bean lecithin has been found to contain derivatised forms of:
  • the carboxylic acids may be saturated or may contain a degree of mono-, di- or polyunsatura- tion (for example triunsatura ion) . It should be noted that, whereas natural plant lecithins are preferred, the invention is by no means limited to them. Synthetic lecithins, whether the two carboxylic acids are the same as or different from each other, may also be used to good effect.
  • Egg lecithin may be isolated from eggs as described by Sinclair in Can. J. Res. 26B 777 (1948) .
  • the preferred soya bean lecithin may be produced commercially, and is frequently obtained as a by-product in the manufacture of soya bean oil (see Stanley in K.S. Markley Soyabeans Vol.II Interscience, New York, U.S.A., 1951, pages 593- 647) .
  • Mixed acid alpha-lecithins may be described by the method of de Haas and van Deenen in Tetrahedron Letters 1960 (No. 9) 1.
  • lecithin or a mixture of lecithins
  • carboxylic acid be applied.
  • soy lecithin and propionic acid such as for example supplied under the trade mark LI-700 by Loveland Industries, Inc. (Greeley, Colorado, U.S.A.) or under the trade mark SPRAYMATE LI-700 by Newman Agrochemicals Limited (Barton, Cambridge, England) .
  • LI-700 contains (on a weight basis) :
  • soy lecithin and propionic acid which may be used are disclosed in US-A-3682653, the contents of which are (to the extent allowed by law) herein incorporated by reference.
  • the phospholipid(s) will be present up to a maximum of 5% by weight (based on the weight of the total macronutrient) . Generally, at least 0.01% phospholipid(s) will be used and usually at least 0.1%. Often the maximum amount will be 1 or 2%.
  • the weight ratio of the phospholipid to carboxylic acid may range from 0.2:1 to 5:1, typically from 0.5:1 to 2:1 and often from 0.8:1 to 1.2:1.
  • a fertilising composition comprising a macronutrient fertiliser and up to 5% by weight phospholipid (based on the total weight of the macronutrient(s) ) comprising lecithin.
  • a fertilising composition comprising a macronutrient fertiliser, a carboxylic acid or its salt and up to 5% by weight phospholipid (based on the total weight of the macronutrient(s) ) .
  • compositions may contain only the ingredients listed, or alternatively may contain additional ingredients.
  • the compositions will generally be aqueous and usually in solution.
  • nitrogen-containing fertiliser it may be possible to apply nitrogen-containing fertiliser at a rate of from 80 to 120 kg N/ha and achieve comparable or greater yields.
  • a method of fertilising plants comprising applying to plant foliage a macronutrient fertiliser and a carboxylic acid or its salt.
  • a macronutrient fertilising composition comprising a macronutrient fertiliser, and a carboxylic acid or its salt.
  • Preferred aspects of the fifth and sixth aspects are as for the first and second aspects, mutatis mutandis.
  • Example 1 The procedure of Example 1 was followed, except that the nitrogen was applied as solid ammonium nitrate prills as a two-thirds dose at first node detectable (29th April, 1987) and a one-third dose on 8th May, 1987.
  • the results are shown in Table 1 and as line B in graph l.
  • Nitrogen fertiliser was applied (at 20, 50, 80, 120 and 180 kg N/ha) in the manner of Example 1. Plots measured 12 metres long and 3 metres wide.
  • Example 2 The procedure of Example 2 was followed, except that solid ammonium nitrate fertiliser was used, without LI- 700, as in Control 1. The results are shown in Table 2. In addition to these controls, a liquid urea solution was applied, without LI-700, at a rate of 20 kg N/ha to give a grain yield of 6.67, which shows close correlation with the value of 6.61 obtained for solid ammonium nitrate: this confirms established data that urea and ammonium nitrate are broadly equivalent in their yield promoting fertilising effects.
  • Example 3 The procedure of Example 3 was repeated, except that the nitrogen was applied as prilled ammonium nitrate without I-700. The results are shown in Table 3 and as line B in Graph 3.
