How Alpha Agri and Agro-Liquid can help improve your alfalfa
What does a crop of alfalfa need?
Good soil fertility is the base for a successful
crop of alfalfa, yet even with that in place, care
needs to be given to maximize its yield and quali-
ty. Alfalfa needs 12 lbs of phosphorus, 50 lbs of
potash, 11 lbs of sulphur, 38 lbs of calcium and a
variety of micro-nutrients per tonne of alfalfa re-
moved! While manure can replace a good part of
this, supplementation is required to fully realize
yield potential while maintaining soil fertility.
When and how should alfalfa be fertilized?
Early spring is the best time to feed your alfalfa
crop. At this time of year the soil is cool and wet;
perfect for growing hay crops but not for nutrient
supply. Soil biology in cool, wet soil is relatively
slow and inactive and does not release enough
nutrition for the high demands of the growing
crop. An early foliar application of ferti-Rain®
12-3-3 (a liquid product specifically designed for
foliar application) along with some micro-
nutrients has been proven to significantly in-
crease both yield and quality.
Along with the foliar application, we also rec-
ommend an application of potassium sulfate .
This adds the required sulphur without the salts
of potassium chloride. Applying urea at the same
time will boost yields, especially if grass is in-
cluded. High, early spring soil moisture quickly
absorbs the potassium and sulphur making it
available early in the growing season.
Applications later in the season fall on dryer
ground and are not absorbed as easily. Early ap-
plication gets the crop off to a strong start
and adds all season fertility.
We also recommend an application of
Humika at planting to help get your crops off
to a strong start.
Aren't all fertilizers basically the same?
No. Salt index is one variation. For example,
potassium chloride has more than twice the
salt index of potassium sulphate. Alfalfa is
moderately sensitive to salt so care needs to
be taken to ensure that products applied do
not harm the crop. AgroLiquid’s fertilizers
are all very low salt index.
AgroLiquid fertilizers are also highly avail-
able due to the polymer coatings which pro-
vide maximum nutrient benefit over time as
your crops require.
Using the right fertilizers, at the right time,
and at the right rate, along with timely ma-
nure applications will provide for healthy
strong alfalfa crops that will provide strong
nutritional yields for many years.
Do Alpha-Agri programs work?
Most certainly, all of AgroLiquid’s fertiliz-
ers are extensively tested at their 930 acre
test farm before being offered for sale.
Many independent producers also conduct
trials to confirm the same results on their
own operations. Alpha Agri’s HumikaTM is
CFIA registered and independent trials have
repeatedly proved its benefits.
