Importance of micronutrients in crop

production

About Micronutrients…

• Needed in very small amounts • Play a vital role in plant growth • Early season deficiencies can lower yield

potential • Soil factors impact availability

What role do they play?

• They ignite life processes in the plant – Photosynthesis – Respiration – Protein synthesis – Growth regulation – And many others!

Manganese deficiency

• Symptoms do not occur on old leaves • Yellowing between veins regularly appears on fully expanded young leaves

Manganese (Mn) • Manganese is central to SPLITTING WATER MOLECULES – a key process in

photosynthesis

• BUT If deficiency is corrected, photosynthesis is restored within hours

Zinc deficiency

• Yellowing/light green between veins

• New leaves are smaller than normal, - internodes are short

The roles of zinc in the plant – too many to count!

Zinc (Zn)

Example – effect of withdrawing and then resuming zinc supply to dry beans

(Cakmak et al, 1989)

Boron deficiency

• No boron leads to inability of the crop to “glue” cell walls together

Boron (B) – essential for the crop to be able to “glue” cell walls together

• Boron helps the crop make the “mortar” that glues plant cells together!

• Called rhamnogalacturan II or RG-II, it is found in plant cell walls

• Normal plant growth depends on the ability of RG-II strands to cross-link with boron and form a network in the cell wall matrix

Role of copper in plants

• Drives photosynthesis and respiration

• Helps convert amino acids to proteins • Formation of lignin in plant cell walls

which contributes to the structural strength of the cells, and the plant

• Copper also affects the flavour, the

storage ability, and the sugar content of fruits

Three nutrient ideas to help you manage your vegetable crops for

a high-performance season

Three ideas for a high-performance season

1) Drive rapid, early and even plant emergence 2) Feed the crop early in the growing season 3) Time in-season applications to meet crop

needs

CONSIDER A SEED-APPLIED NUTRIENT PACKAGE FOR RAPID, EARLY AND EVEN EMERGENCE

Idea #1

• Patented, seed-applied fertilizer – Zinc, Manganese, Iron

• Safely delivers essential nutrients directly to the seed

• Nutrients available as soon as the seed germinates

Rapid, even emergence

Head Lettuce Earlier emergence as well as better stand

uniformity at germination

Rapid, even emergence

Artichokes Much higher stand count and

uniformity at germination

8 plants/2 m row 16 plants/2 m row

Rapid, even emergence

Green Leaf Lettuce Earlier Stand Emergence

5-6-13

55 plants/m row 60 plants/m row

More even plant stand 6.25.13

Artichokes More crop uniformity =

Better Stand

More even plant stand 5-21-13

Head Lettuce More even emergence means better stand uniformity

PROTINUS treatment resulted in consistent 22 – 23 plants per m row

No Clogging or Impeding of Vacuum planter with PROTINUS

DELIVER NUTRIENTS TO YOUR CROP AS EARLY AS POSSIBLE

Idea #2

Your crop = factory

• Job is to collect sunlight and make sugar

• How to make factory run faster, earlier, run longer and produce more

Historically – only two options to feed micronutrients to your crops

1. Apply an ineffective and sparse soil application with granules

2. Wait until emergence and apply a foliar product

• Neither of these are ideal…

With soil applications, nutrients move naturally from roots to aboveground plant parts as the plant grows

Zn

But, the issue with soil applied granular micronutrients has been “scarcity”

Zn

With foliar applications, difficult to attain movement from treated foliar to new growth that arises after spraying

DDP Nutrients deliver early nutrition

+ Better distribution

with EvenCoat™ Technology

= Earlier delivery of

nutrients 153 granules of fertilizer throughout rooting depth,

all coated with DDP Micronutrients mean better root interception (15x5x3 inch soil profile)

2 granules of micronutrient are sparsely distributed and

leave micronutrient fertilization to chance

TIME YOUR IN-SEASON APPLICATIONS TO MATCH THE CROP’S NEEDS

Idea #3

WHEN do Plants Need a Micronutrient? . . . Timing?

• Answer: Delivery needs to occur BEFORE needed for biological processes

• Fixing deficiencies or “just-in-time” applications WILL rob yield

• The micronutrient is needed WEEKS before deficiency symptoms

Why is Timing Important?

• Most micronutrients DO NOT move well within the plant or soil

Immobile within PLANT Boron? Zinc Copper Manganese Iron

Immobile within SOIL Zinc Copper Manganese Iron Phosphorus

A new way of correcting deficiencies

• Spoon feeding micronutrients at several points in the season

• A “multifeed” approach is an excellent nutrient management tool

Choose all or some of these Wolf Trax “tools” for delivering nutrients to the crop

FIRST SPOON FEED TO THE CROP

Fed to the crop using a seed application

SECOND SPOON FEED TO THE CROP

Fed to the crop by coating the DDP onto dry fertilizer or mixing with liquid fertilizer

THIRD + SPOON FEED TO THE CROP

Fed to the crop using a foliar application with liquid fertilizer, or recommended pesticides or alone

Wolf Trax DDP – A Foliar Solution • FlexUse™ means that the same Wolf Trax

DDP’s that can be used to coat your N, P, and K are also easy to use in foliar applications – Mix easily – Crop safe

Wolf Trax nutrients offer fast and extended feeding

Containing at least two sources of mineral in each product, Wolf Trax Nutrients and the patented Dual-Action availability offer fast and extended feeding to your crop.

Considerations for Calcium DDP

Even in controlled environment situations, quality issues can occur Calcium can’t get to the sink spot due to rapid growth and plant physiology Applying Calcium DDP can help alleviate blossom end-rot and improve yields and quality.

Considerations for Calcium DDP

Calcium is a key nutrient in proper tuber development in potato. Calcium can’t get to the sink spot due to rapid growth and plant physiology Applying Calcium DDP can help alleviate hollow-heart and improve yields and quality.

Calcium DDP, used in a liquid application enhances tomato

growth and production in Mexico.

Calcium DDP applied at 1.3 lb/ac in 2 quarts of 2-0-25 helps solidify cell walls and make fruit firm for shipping.

California, June 2013

Field Results with Wolf Trax DDP Improving Yield and Quality

• Early fertility is important, but later season application can give the crop the boost needed to optimize yield.

• This producer used a fertigation application of Boron DDP to enhance his corn yield.

Boron DDP helped fill the ear right to the end. In this field, the DDP program helped the grower boost

his yield by over 30%
