Abstract

Processes and compositions are disclosed that enhance crop production, increase plant defensive processes and/or decrease the level of plant pathogens. The compositions comprise a microbial composition and liquid fertilizer, preferably a liquid fertilizer that contains at least soluble nitrogen. The composition can be applied immediately to soil, foliage, seeds or seedlings. Alternatively, the composition may be activated by incubation for up to about seven days to form an activated composition. The incubation conditions influence the properties of the consortium after incubation. In one embodiment, the compositions comprise one or more lactic acid producing bacteria, one or more nitrogen fixing bacteria, and liquid fertilizer comprising soluble nitrogen. In preferred embodiments, there are multiple genera and/or species of lactic acid bacteria and nitrogen fixing bacteria. In a particularly preferred embodiment, the composition comprises HYTa in liquid fertilizer.

Claims

1. A process comprising contacting soil, seed, seedling, or plant foliage with a composition comprising the microbes in HYTa (ATCC Patent Deposit Designation PTA-10973) and liquid fertilizer.

2. The process of claim 1, wherein said microbial composition is activated.

3. The process of claim 1, wherein said microbial composition is activated by incubation in said liquid fertilizer prior to said contacting.

4. The process of claim 3, wherein said incubation is for 24 to 168 hours prior to said contacting.

5. The process of claim 1, wherein said contacting is of said soil to form treated soil.

6. The process of claim 1, wherein said liquid fertilizer comprises soluble nitrogen.

7. The process of claim 6, wherein said soluble nitrogen comprises an organic soluble nitrogen source or a nitrogen-containing inorganic salt.

8. The process of claim 7, wherein said nitrogen-containing inorganic salt comprises ammonium hydroxide, ammonium nitrate, ammonium sulfate, ammonium pyrophosphate, ammonium thiosulfate, or combinations thereof.

9. The process of claim 7, wherein said organic soluble nitrogen source comprises urea.

10. The process of claim 1, further comprising contacting the soil, seed, seedling, or plant foliage with HYTb and/or HYTd, wherein said HYTb is the liquid fraction obtained from the fermentation of chitin-containing organisms by HQE (ATCC Patent Deposit Designation PTA-10861) and said HYTd is the liquid fraction obtained from the fermentation of chitin in HYTb by HQE.

11. The process of claim 1, further comprising contacting the soil, seed, seedling, or plant foliage with HYTc, wherein said HYTc is the solid fraction obtained from the fermentation of chitin-containing organisms with HQE (ATCC Patent Deposit Designation PTA-10861).

12. The process of claim 1, further comprising contacting the soil, seed, seedling, or plant foliage with (i) HYTb and/or HYTd and (ii) HYTc, wherein said HYTb is the liquid fraction obtained from the fermentation of chitin-containing organisms with HQE (ATCC Patent Deposit Designation PTA-10861), said HYTc is the solid fraction obtained from the fermentation of chitin-containing organisms with HQE (ATCC Patent Deposit Designation PTA-10861), and said HYTd is the liquid fraction obtained from the fermentation of chitin in HYTb by HQE.
