Formulation of phosphorus fertilizer for plants

A concentrated phosphorous-acid salt containing fertilizer comprising a buffered composition comprising a salt of a phosphorous-containing acid such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage acceptable pH for phosphorus uptake and wherein said salt of said phosphorous-containing acid is present in the concentrated phosphorous-acid salt containing fertilizer in an amount that contains phosphorus equivalent to about 0.30 kg/L or greater P2O5.

A concentrated phosphorus fertilizer comprising available phosphorus in an amount that contains phosphorus equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a phosphorous-containing species which is a member selected from the group consisting of phosphorous-containing acid, a salt of phosphorous-containing acid, and combinations thereof, such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage-acceptable pH for phosphorus uptake and wherein said phosphorous-containing species is present in the concentrated phosphorus fertilizer in an amount sufficient to provide said fertilizer with available phosphorus equivalent to about 0.30 kg/L or greater P2O5.

A method of providing phosphorus to a plant comprising:

• (a) diluting a concentrated phosphorus fertilizer comprising available phosphorus in an amount equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a phosphorous-containing species which is a member selected from the group consisting of phosphorous-containing acid, a salt of phosphorous-containing acid, and combinations thereof;
• and
• (b) applying said use-dilution fertilizer to foliage of a plant.

A method of preparing a concentrated phosphorus fertilizer comprising available phosphorus in an amount equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a member selected from the group consisting of phosphorous-containing acid, salt of phosphorous-containing acid, and combinations thereof, such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage-acceptable pH for phosphorus uptake, said method comprising:

• contacting with a base a quantity of said phosphorous-containing acid, thereby forming said buffered composition.

A concentrated phosphite containing fertilizer comprising a buffered composition comprising a phosphite such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage acceptable pH for phosphorus uptake and wherein said phosphite is present in the concentrated phosphite containing fertilizer in an amount that contains phosphorus equivalent to about 0.30 kg/L or greater P2O5.

A concentrated phosphorus fertilizer comprising available phosphorus in an amount equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a phosphite, such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage-acceptable pH for phosphorus uptake and wherein said phosphite is present in the concentrated phosphorus fertilizer in an amount sufficient to provide said fertilizer with available phosphorus equivalent to about 0.30 kg/L or greater P2O5.

A method of providing phosphorus to a plant comprising:

• (a) diluting a concentrated phosphorus fertilizer comprising available phosphorus in an amount equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a phosphite present in the concentrated phosphorus fertilizer in a quantity sufficient to provide said fertilizer with available phosphorus equivalent to about 0.30 kg/L or greater P2O5, to form a substantially fully solubilized use-dilution fertilizer having foliage-acceptable pH for phosphorus uptake;
• and
• (b) applying said use-dilution fertilizer to foliage of a plant.

A concentrated phosphorus fertilizer comprising available phosphorus in an amount equivalent to about 0.30 kg/L or greater P2O5, said fertilizer comprising a buffered composition comprising a phosphorous-containing species which is a member selected from the group consisting of phosphorous-containing acid, a salt of phosphorous-containing acid, and combinations thereof, such that when said composition is diluted with water having a pH as low as about 6.5 at a ratio as high as about 1 part fertilizer to about 40 parts water, there is formed a substantially fully solubilized use-dilution fertilizer having a foliage-acceptable pH for phosphorus uptake.
