Abstract
An agricultural adjuvant includes microfibrillated cellulose, a dispersant or wetting agent, in a liquid carrier that has been subjected to shear conditions. The resultant adjuvant displays useful rheological structure and the adjuvant is added to agricultural formulations to stabilize and impart useful rheology to the formulations.

-33. (canceled)
A kit comprising:
- an adjuvant composition comprising:
- 0.01% by weight to 5.0% by weight of a chemically unmodified microfibrillated cellulose (MFC);
- a surfactant or dispersant;
- and
- a liquid carrier,
- wherein the adjuvant composition is formed by subjecting the MFC, the liquid carrier, and the surfactant or dispersant to shear conditions comprising shearing the adjuvant composition at 5,000 RPM to 10,000 RPM with a blade for at least 4 minutes to achieve a storage modulus (G′) of at least 57 Pascals and a loss modulus (G″) of at least 9.7 Pascals;
- and
- instructions for adding the adjuvant to a fertilizer or high ionic strength solution to create an agricultural formulation, wherein the high ionic strength solution comprises at least 5% saturation of a functional ion.

A composition comprising:
- (a) less than 0.1% by weight of a chemically unmodified microfibrillated cellulose (MFC);
- (b) a surfactant or dispersant;
- and
- (c) a liquid carrier,
- wherein the composition is subjected to shear conditions sufficient to increase the storage modulus (G′) to at least 57 Pascals or the loss modulus (G″) to at least 9.7 Pascals of the adjuvant composition, the shear conditions comprising 5,000 RPM to 10,000 RPM with a blade.

A method comprising:
- (i) providing an adjuvant composition comprising:
- (a) less than 0.1% by weight of a chemically unmodified microfibrillated cellulose (MFC);
- (b) a surfactant or dispersant;
- and
- (c) a liquid carrier;
- and
- (ii) subjecting an adjuvant composition to shear conditions sufficient to increase the storage modulus (G′) or the loss modulus (G″) of the adjuvant composition
- wherein the shear conditions comprise shearing the adjuvant composition at 5000RPM to 10,000 RPM with a blade for at least 4 minutes to achieve a G′ of at least 57 Pascals and a G″ of at least 9.7 Pascals.
