“…The responses to fresh P on soils with 9, 15 and 25 mg P/kg in Table 11 agree remarkably well with those of Draycott et al (1971) who found a response of 1-3 t/ha for a few soils near 10 mg P/kg and much smaller increases, 0-3 and 0-2 t/ha, at soluble P values of 11-15 and 16-25 mg/kg respectively. Our results support the recommendation made by Draycott et al (1971) that only small insurance dressings of P are needed for sugar beet grown on soils with more than 15 mg soluble P/kg.…”

“…The average response to this P dressing in our experiments, 710 kg sugar/ha, was much larger than that, 140-200 kg/ha, reported by Draycott et al (1971). However, 25% of our soils had less than 9 mg soluble P/kg whereas only 6 % of their soils were in this category.…”

“…Results from this experiment in Suffolk can be compared with those of Draycott et al (1971) from experiments in eastern England and those of Johnston et al (1976) from Bedfordshire. In all these experiments the yield given by 55 kg P/ha was measured or could be calculated.…”

“…E. JOHNSTON AND OTHERS Subsequently Boyd and co-workers summarized many ADAS experiments on potatoes and showed that responses to fresh P diminished as bicarbonatesoluble P increased (Farrar & Boyd, 1976;Archer, Victor & Boyd, 1976;Webber, Boyd & Victor, 1976). Similarly, experiments with sugar beet showed that between-site variance in yield response to P fertilizers was best accounted for by the amounts of bicarbonate-soluble P in the soils (Draycott, Durrant & Boyd, 1971). Most of the above experiments were made on commercial farms so that yield differences reflected variations not only in bicarbonate-soluble P and climate but also in cultivation and management practices.…”

Effects of soil and fertilizer P on yields of potatoes, sugar beet, barley and winter wheat on a sandy clay loam soil at Saxmundham, Suffolk

et al. 1986

During 1899-1964 various levels of 0-5 M sodium bicarbonate-soluble P had been established in an experiment on a sandy clay loam (pH 6-5-7-0) at Saxmundham, Suffolk. Modification made between 1965 and 1968 widened the range of soluble P values to 3-67 mg/kg. Relationships between these soluble P values and yields of potatoes and sugar beet in 1969-74 and cereals in 1970-7 were assessed. Responses by potatoes and sugar beet to freshly applied superphosphate were also determined at each level of soluble P. Residual effects of these dressings and responses to fresh superphosphate between 1974 and 1976 were measured by barley. Two amounts of N were tested on spring barley in 1976-7 and two cultivars of winter wheat were grown in 1977 and yields related to soluble P.Relationships between yields and soluble P were described by an asymptotic regression equation. This model represented the measured yields well for all crops except barley, in one 4-year-period, when there were insufficient data at low soil P values and a linear regression model was fitted. The asymptotic model was used to estimate plateau yields each year and soluble P values at which yields were less than plateau values by one standard error. Average plateau yields, and associated soluble P values were: potatoes, 43 t/ha and 25 mg P/kg; sugar (from sugar beet) 6-8 t/ha and 20 mg P/kg; spring barley, given 63 kg N/ha, 4-7 t/ha and 25 mg P/kg; barley given 94 kg N/ha, 5-3 t/ha and 33 mg P/kg; winter wheat, 6-5 t/ha and 20 mg P/kg.The model was further used to estimate responses to dressings of superphosphate at three levels of soluble P (9, 15 and 25 mg/kg) in the soils. Yield responses to 55 kg P/ha were 3-9, 2-1 and 1-8 t tubers/ha and 1-1, 0-3 and 0-0 t sugar/ha, for potatoes and sugar beet respectively, at the three levels of soluble P.On impoverished soils (soluble P < 10 mg/kg) even the largest fresh applications of broadcast superphosphate did not raise yields to those achieved on enriched soils (soluble P > 25 mg P/kg) in the absence of fresh phosphate.Soluble P in the soils accounted for much of the within-year variation of yields and estimated reliably and quantitatively the value of phosphate residues derived from both superphosphate and farmyard manure which had been applied in varying amounts and at different times between 1899 and 1976.

Phosphorus Fertilization of Sugarbeets

Sugarbeets (Beta vulgaris L.) have been fertilized with phosphorus (P) in the U.S.A. for the past 30 to 40 years. During this period, numerous studies on P fertilization rates and application methods have been conducted. Much of this information has been summarized (12,14,15, 4). 1Recent soil test data from England and the U.S.A. suggest that the available P levels in many soils are sufficient for maximum root and sucrose production without P fertilization. Detrimental effects of P fertilization at excessive soil P levels have been reported (6, 5) but not all data support these conclusions (12). Increasing fertilizer costs have also made it essential that growers have adequate guidelines upon which to base fertilizer applications. Information has been limited in Idaho for establishing an adequate soil test P level for optimum sugarbeet production. With this as background, we conducted two field experiments evaluating 1) the P fertilizer requirements of sugarbeets at different soil test P levels, and 2) the effects of P fertilization on soils already containing adequate available P levels. Methods and MaterialsField experiments were conducted in 1972 and 1975 on the Portneuf silt loam (Xerollic Calciorthid) soil. This soil has a weakly cemented hardpan beginning at the 16-to 18-in depth which restricts downward root growth but not water movement. The residual soil P levels (Table 1) in 1972 resulted from a P fertilization experiment conducted on dry beans in 1971, whereas those in 1973 were established by rototilling into the soil various P fertilizer rates in the fall of 1972 after the harvest of a spring wheat crop. The bean straw residue from 1971 and the wheat straw residue from 1972 were plowed down in the spring, prior to the 1972 and 1973 experiments, respectively. The spring applications of N (34-0-0) and P (CSP, 0-45-0) fertilizers were incorporated into the seedbed before planting. The amount of N fertilizer applied was determined by the method outlined by Carter, et al. (3).Soil samples were taken from each residual P treatment in 9-in increments to the 18-in depth before t4 spring fertilizer application. The samples were air-dried and the soil test P level (STPL) was measured by the 'Contribution from the Western Region, Agricultural Research Service, USDA; University of Idaho College of Agriculture Research and Extension Center cooperating.'Soil Scientists, Snake River Conservation Research Center, Kimberly, Idaho SSW 'Numbers in parentheses refer to literature cited.
