Field of the Invention The present invention generally relates to a method of treatment of plants. More particularly, the invention relates to an iMproved me-thod of delivery of plant nutrients.
Back~round of the Prior Art The supply and absorption of chemical compounds needed for growth and me-tabolism may be defined as nutri-tion and the chemical compounds required by an organism t'ermed nutrients. The mechanisms by which nutrients are converted to cellular material or used for energetic purposes are metabol'ic processes. The term 'metabolism' encompasses the various reactions occurring in a living cell in order to maintain life and growth. Nutrition and metabolism are thus very closely interrelated.
The essential nutrients required by green plants are exclusively of inorganic nature. In -this respect green plants differ fundamentally from man~ animals and a number of microorganisms, which additionally need organic compounds as foodstuffs. An essential element may be defined as one which is required for -the normal life cycle of an organism and whose functions can not be substituted by other chemical compounds. In addition, the element must be shown to be direct]y involved in nutri-tion, as for example as a constituent of an essential enzyme system. Based on this definition, -the following chemical elements are now known to be essential for higher plants:

The plant nutrients may be divided into macro-nutrien-ts and micronutrients. Macronutrients are found and needed in plants in relatively higher amounts than micronutrients.

~ollowing this classification based on the element content in plant material, the following elements may be defined as macronutrients: C, H, O, N, P, S, K, Ca, Mg, Na and Si. The micronutrients are: ~e, Mn, Cu, Zn, Mo, B and Cl. This division of the plant nutrients into macro- and micronutrients is somewhat arbitrary and in many cases differences between the contents of macro-nutrients and micronutrients are considerably ]ower than the example cited above.
The process o~ nutrient uptake and assimilation by plants is not fully understood, although a number of -theories of ion uptake and transport are known, see for example, Mengel et al, Principles of Plant Nutri~tion, Chapter 3, "Nutrient Uptake and Assimilation", Interna-tional Po-tash Institute, Bern (1978).

SUMMARY OF THE INVENTION
I have now discovered an improved method of delivery of p]ant nutrients to plants through the use of a compound which, when combined with a plant nutrients, enhances the uptake and assimilation of the plant nutrient in the plant. The composition containing the delivery-enhancing compound and plant nutrient may be applied to the plant in the conventional manner.
The invention, -therefore, relates to an improved method of delivery of plant nutrients comprising contacting a plant with a composi-tion comprising an effective amount of a plant nutrient and an effective, delivery-enhancing amount of a compound having the structural formula R' (CH2~m ~ 2 n Where R' is H or a lower alkyl group having 1-4 carbon atoms, m is 3-7, n is ~-17, and R is -CH3, ~ R~
C . ~ ' -N~ r------(CH2)m where R'l is H or Halogen and R' has the same meaning as above.
The invention also relates to compositions comprising an effective amount of a plant nutrient and an effective, delivery-enhancing amount of a compound having the structural formula n (CH2)m ~ - (CH2)n - R

DETAILED DES~kl~lION OF THE INVENTION
The l-substituted azacycloalkan-2-ones used in this inven-tion together with their methods of synthesis are disclosed in U.S.
Patent No. 4,316,893.
The amount of l-substituted azacycloalkan-2-one which may be used in the present invention is an amount effective for enhanc-ing the delivery of a plant nutrient to a plant. Generally, an effective amount ranges between about 0.01 to about 99.9 and pre-ferably about 0.1 to 10 percent by weight of the composition.
Plant nutrients which may be used in this invention in-clude conventional macronutrients and micronutrients previously described including essential as well as non-essential plant nutrients. Examples of nutrients include, but are not limited to, the primary plant foods: nitrogen including ammonia and nitrate ions, phosphorus (phosphoric acid), potassium (potash); the second-ary plant-food elements: calcium, magnesium and sulfur; and the trace elements: manganese, boron, copper, zinc, iron, molybdenum and chlorine. The form of 8C)~2~
the foregoing nutrients may be in any conventional form, see, for example, McVickar et al, Using Commercial Fertilizer, The Interstate Publishers, Danville9 Illinois (1978).
The method of application of the plant nutrient compositions described herein is conventional. See~ for example, McVickor et al, Using Commercial Fertilizers, Chapter XIV, "Methods of Applying Fertilizers".
The precise amount of the plant nutrient compo-sition to be delivered to-the plant will obviously be an effective amount for the desired result expected therefDom.
This, of course, will be ascertained by the ordinary skill of the practitioner. Due to enhanced activity which is achieved, the amount of plant nutrients may often be decreased from that generally applicable. In accordance with the usual prudent formulating practices, a dosage near the lower end of the useful range of the particular agent may be employed initially and the dosage increased as indicated from the observed response.
Nitrogen N Iron Fe Chlorine Cl 5 Phosphorus P Manganese Mn Sodium Na Sulfur S Copper Cu Silicon Si Cobalt Co The list of essential elements shown above may well not be complete and other elements, in very low concentrations, may yet be shown to be essential for higher plants. ~or some microorganisms, for example, vanadium (V) has now been established as an essential element.
The plant nutrients may be divided into macro-nutrien-ts and micronutrients. Macronutrients are found and needed in plants in relatively higher amounts than micronutrients. The plant tissue content of the macronutrient N, for example is over a thousand -times greater than the content of -the micronutrient Zn.
~ollowing this classification based on the element content in plant material, the following elements may be defined as macronutrients: C, H, O, N, P, S, K, Ca, Mg, Na and Si. The micronutrients are: ~e, Mn, Cu, Zn, Mo, B and Cl. This division of the plant nutrients into macro- and micronutrients is somewhat arbitrary and in many cases differences between the contents of macro-nutrients and micronutrients are considerably ]ower than the example cited above.
The process o~ nutrient uptake and assimilation by plants is not fully understood, although a number of -theories of ion uptake and transport are known, see for example, Mengel et al, Principles of Plant Nutri~tion, Chapter 3, "Nutrient Uptake and Assimilation", Interna-tional Po-tash Institute, Bern (1978).

SUMMARY OF THE INVENTION
I have now discovered an improved method of delivery of p]ant nutrients to plants through the use of a compound which, when combined with a plant nutrients, enhances the uptake and assimilation of the plant nutrient in the plant. The composition containing the delivery-enhancing compound and plant nutrient may be applied to the plant in the conventional manner.
The invention, -therefore, relates to an improved method of delivery of plant nutrients comprising contacting a plant with a composi-tion comprising an effective amount of a plant nutrient and an effective, delivery-enhancing amount of a compound having the structural formula R' (CH2~m ~ 2 n Where R' is H or a lower alkyl group having 1-4 carbon atoms, m is 3-7, n is ~-17, and R is -CH3, ~ R~

DETAILED DES~kl~lION OF THE INVENTION
The l-substituted azacycloalkan-2-ones used in this inven-tion together with their methods of synthesis are disclosed in U.S.
Patent No. 4,316,893.
The amount of l-substituted azacycloalkan-2-one which may be used in the present invention is an amount effective for enhanc-ing the delivery of a plant nutrient to a plant. Generally, an effective amount ranges between about 0.01 to about 99.9 and pre-ferably about 0.1 to 10 percent by weight of the composition.
Plant nutrients which may be used in this invention in-clude conventional macronutrients and micronutrients previously described including essential as well as non-essential plant nutrients. Examples of nutrients include, but are not limited to, the primary plant foods: nitrogen including ammonia and nitrate ions, phosphorus (phosphoric acid), potassium (potash); the second-ary plant-food elements: calcium, magnesium and sulfur; and the trace elements: manganese, boron, copper, zinc, iron, molybdenum and chlorine. The form of 8C)~2~
the foregoing nutrients may be in any conventional form, see, for example, McVickar et al, Using Commercial Fertilizer, The Interstate Publishers, Danville9 Illinois (1978).
The method of application of the plant nutrient compositions described herein is conventional. See~ for example, McVickor et al, Using Commercial Fertilizers, Chapter XIV, "Methods of Applying Fertilizers".
The precise amount of the plant nutrient compo-sition to be delivered to-the plant will obviously be an effective amount for the desired result expected therefDom.
This, of course, will be ascertained by the ordinary skill of the practitioner. Due to enhanced activity which is achieved, the amount of plant nutrients may often be decreased from that generally applicable. In accordance with the usual prudent formulating practices, a dosage near the lower end of the useful range of the particular agent may be employed initially and the dosage increased as indicated from the observed response.
