1 Cool Season Vegetables and Strawberry Response to Phosphates Research and Observations over the last Ten Years David Holden

2

3 Introduction My Experience Over 700 trials in the past ten years in nutrient and pest management for fruit, nut, and vegetable production. Over 35 trials in the past ten years with phosphate based fertilizers on vegetables, strawberries, grapes, and trees.

4 Introduction All phosphate trials were conducted in the coastal counties of Monterey, San Luis Obispo, Santa Barbara, and Ventura Both ortho and poly phosphates were involved. Sometimes organic acid additives were involved, along with phosphorus protecting products.

5 University Recommendations University of California, ANR Publication 8098, Nutrient Management In Cool Season Vegetables

6 What are the Issues with ph Phosphorus Availability Temperature Cation inhibition Calcium Zinc Etc.

7 How Soil ph affects P2O5

8 Cool Soils Cool soils may induce phosphorus deficiency With cool soils you have slower root growth and development Less opportunity for roots to come in contact with the phosphorus they need at this time Limiting phosphorus in cool seasons exacerbates the ability for cool season vegetables to grow.

9 Cation Inhibition Calcium and zinc cations (and others) have an affinity for PO4, phosphate anion. They form calcium and zinc phosphate precipitates which are now hard to resolubilize for root uptake. But this also helps reduce leaching of PO4 from the soil solution.

10 Plant Phosphorus Utilization Forms nucleic acids (DNA and RNA) Used in the making of the chemical energy molecules of ATP and ADP. Through this transfer of chemical energy it is utilized in new growth and reproduction. Note that dry leaf analysis of P2O5 in young leaves is always higher than that found in older leaves.

11 Symptoms of Phosphorus Deficiency Slow growth, stunted plants Purplish coloration on foliage of some plants (older leaves first) Dark green coloration Delayed maturity Poor fruit or seed development

12 Not So Obvious Symptoms of Phosphorus Deficiency Poor root development Reduced production Sizing reduction Fruit set reduction

13

14 Phosphate vs. Phosphite or Phosphoric Acid vs. Phosphorous Acid One is the source for a fertilizer, the other is a source for a fertilizer and a fungicide. PO4 vs. PO3. PO3 will (?) oxidize eventually to PO4 Know the difference. There is still quite a bit of confusion regarding these source products

15 Four Recent Trials with Phosphates in Peppers and Strawberries. Phosphates generally placed in addition to the grower s standard practices which may include pre-plant and in-season phosphate applications. All crops grown on tape, which allows for precise in season placement of phosphate.

16 Early Spring 2010 Peppers Pre-Plant poly phosphate applied as band under seedline on 4/27/10 Pre-Plant Phosphorus (Olsen Method) 41 ppm Treat 1 untreated Treat lb/ac P2O5 as Treat 3 55 lb/ac P2O5 as Proprietary Treat 4-30 lb/ac P2O5 as Proprietary Planted 5/5/10

27 Conclusions Additional Early Season applications of P2O5 did help increase early season production As soils warmed and crop finished out the end season differential was not as great Early season production does return the grower a better price per flat.

34 Conclusions Additional Early Season applications of P2O5 did help increase early season production Spring of 2010 was cooler than previous spring. With phosphate source removed in February, reduction in production was observed.

35 General Conclusions General production increases of 5-10% for coastal vegetables and strawberries when additional phosphate added to the growers standard programs in the fall, winter and early spring. These have occurred on soils that are not generally P2O5 deficient ppm P2O5 soils Similar results not observed in the summer time. No surprise that we are seeing a response on colder soils It is a surprise that what the grower s thought was sufficient supplies of phosphorus was not so.
