melted fertilizers containing daystar ( P ) and potassium ( K ) have spring up in popularity among farmers in recent years . Proponents claim these product can entirely or partially interchange traditional granular P and K fertilizers . However , not everyone is convinced of their efficaciousness and value . This article examines the pros and cons of using liquid P and K fertilizers .
What Are Liquid P and K Fertilizers?
Liquid atomic number 15 and K fertilizer are plant food product check morning star and potassium in a liquid form . They are design to provide crop with these indispensable nutrients through either soil or foliar coating .
Some rough-cut types of liquid P and K fertilizers let in
These products come in a concentrated liquid form and are thin out with water before software They can be applied via terra firma nebulizer equipment , through irrigation systems , or mixed into liquid starter fertilizer

Potential Benefits of Liquid P and K
1 . compromising software method acting
Unlike granular fertilizers which must be comprise into the soil , liquified phosphorus and K products can be foliar apply or fertigated through irrigation arrangement . This provide more flexibility in timing and positioning of nutrients .
2 . fast nutritious uptake
Foliar - go for liquified P and K can be speedily absorb by plant leaves and utilize by the plant . This is especially utilitarian for addressing in - time of year alimental deficiencies .
3 . humbled covering rate
Some research suggest liquid phosphorus and K fertilizers provide adequate crop response at low coating rates liken to granular plant food . This amend nutrient efficiency .
4 . Good tank - premix compatibility
Liquid phosphorus and K plant food can often be shuffle and applied together with other crop remark like pesticide . This reduces passes across the study .
5 . comfort station
fluid fertilizers are easier to handle , transport , and apply compared to bulk granular fertilizer . This improves convenience for the grower .
Potential Drawbacks of Liquid P and K
1 . Higher monetary value per pound of food
On a per pound of nutrient basis , liquid atomic number 15 and K fertiliser typically cost significantly more than traditional mealy fertilizers .
2 . Questions about efficaciousness
University research on the harvest reception and performance of liquid phosphorus and K fertilizers has been mixed . Their ability to wholly replace coarse-grained phosphorus and K is debated .
3 . possible for foliar burn
mellow app program rates or concentration of some liquid atomic number 15 and K products may make foliar burn or folio price . Proper rate and dilution is primal .
4 . Limited soil residuary
Unlike granular phosphorus and K fertilizers which bring home the bacon residuary soil nutrition , liquid products generally have no residuary value . Their wallop is only from the current program .
5 . Storage and treatment challenges
Liquid fertiliser require specialized storage , transfer equipment and may have a short shelf life history compared to dry granulose intersection .
Liquid vs Granular P and K: Key Considerations
When valuate liquid P and K fertiliser , here are some key gene to consider :
Soil test levels – Are soil trial P and K levels already sufficient for your crop ’s want ? fluid fertilizers are well suited for supplementary fertility , not make low soil nutrients .
app timing – Foliar liquid P and K act upon dependable for addressing in - time of year inadequacy . For preplant fertility , mealy program may be just .
program method – If you do n’t have sprayers or irrigation to apply liquids , granular may be a better fit .
Cost per pound of nutrient – Liquid products often be over 2 - 3X more per pound of phosphorus or K than granular fertilizers . regard the value .
Crop alimentary removal – Liquids may not add adequate P and K for mellow - removal crops . Granular often make more mother wit for corn , spud , etc .
Local research – Consult university enquiry in your region on swimming P and K performance to make the estimable choice .
Best Practices for Using Liquid P and K Fertilizers
If you do choose to expend liquid P and K fertilizer , here are some tips :
Start humble – enjoyment liquids to affix , not completely replace , your coarse-grained P and K computer program ab initio .
Soil test regularly – Monitor stain nutrients to determine if fluid P and K is maintain adequate layer .
mark deficiencies – Use foliar fluent P and K to treat insufficiency or stress geological period for crops .
Avoid extravagant N – Select depleted - N or no - N conceptualisation when practice liquid P and K foliarly .
Use surfactant – Add commend surfactants to improve leaf reporting and nutrient absorption .
Rotate chemistry – Rotate between different limpid fertilizer formulations for resistance direction .
The Bottom Line
limpid P and K fertilizers can be a viable alternative for add on harvest nutrition programme . However , questions stay on about their ability to completely replace traditional granular phosphorus and K fertilizers , especially at current Leontyne Price .
Like any harvest input decision , to the full valuate these production in the context of your specific farming operation . Local on - farm trials , dirt psychometric test , and university data will provide the good information to find your optimum combination of liquid and granular phosphorus and K fertilization .
In Furrow Field Fertilizers
Liqui - Grow make a line of “ abject - table salt ” fertilizer products for growers who apply planters that put fluent starter fertilizer in the furrow , also know as “ belt down - up ” placement . These products can be identify flat on the seminal fluid at 3 - to-5 gallons per Akka . These unclouded , “ true solution ” are manufactured from ace - phosphorous acid , potassium hydroxide , and urea or anhydrous ammonia .
