All reports for tree fruits or grapes.
Message:
For tree fruits and grapes, soil tests are
used as the basis for fertilizer requirements only for new plantings. Requirements
for established plantings should be based on leaf or petiole analysis.
- All reports for tomatoes or rutabagas with magnesium
tests of less than 100.
Message:
For
tomatoes and rutabagas on soils with magnesium tests of less than 100, the amount
of potash recommended should be adjusted downward from the amounts shown to a
minimum of 50% at a magnesium test of 50.
-
All reports with no crop given.
Message:
Since
fertilizer requirements are specific to each crop, we cannot provide requirements
unless you specify a crop
-
All reports
with established hay or pasture over 1/3 legume for the counties of Dufferin,
Peel, N or S. Simcoe, Muskoka, York, Ontario, Durham, Victoria, Haliburton, Northumberland,
Peterborough, Lennox & Addington, Prince Edward, Hastings and Frontenac.
Message:
Perennial legumes such as alfalfa frequently
require boron at 1 to 2 kg/ha each year on loam soils, sandy loams, and sands
in your area. See the forage section of the OMAFRA Agronomy Guide for Field Crops,
Pub. 811.
-
All reports with established
hay or pasture over 1/3 legume on coarse textured (c) soils from counties not
listed in message #4.
Message:
Perennial legumes
such as alfalfa may require boron at 1 to 2 kg/ha each year on sandy loam soils
and sands. See the forage section of the OMAFRA Agronomy Guide for Field Crops,
Pub. 811.
-
All reports with manganese
index less than 16 for oats, wheat, wheat, barley, triticale, soybeans, onions,
lettuce and beets.
Message:
Manganese deficiency
can be prevented, and frequently corrected, by spraying the crop with 2 kg manganese/ha
in 200 L of water. Manganese sulphate is the recommended source and should be
used with a spreader-sticker. When deficiencies are severe, two or more spray
applications may be necessary. Soil applications of manganese are inefficient
and not recommended.
-
All reports with
manganese index less than 8 and for crops not listed in message 6.
Message:
Your manganese soil test is quite low but
manganese deficiency is not expected on this crop. If symptoms of manganese deficiency
appear on the leaves, spray with 2 kg manganese/ha in 200 L of water. Manganese
sulphate is the recommended source and should be used with a spreader sticker.
Soil applications of manganese are inefficient and not recommended.
-
All reports for crops other than corn or onions with zinc
index less than 8.
Message:
Your zinc soil
test is very low but zinc deficiency is not expected on this crop. If zinc deficiency
symptoms do appear, a zinc spray may be applied to the crop.
-
All reports for corn or onions with zinc index less than 15.
Message:
When OMAFRA accredited zinc index is below 15, corn and onions
may require zinc. Zinc may be applied at 4 to 14 kg zinc/ha (not more than 4 kg
banded). The 14 kg rate should be sufficient for up to 3 years. Foliar sprays
may also be used.
-
Report with manure
applied where rates shown on the information sheet are below 5 t/ha or 10 cubic
metres/ha.
Message:
We have adjusted fertilizer
requirements for higher rates of manure than you have reported. It is almost impossible
to apply rates less than 5 t/ha or 10 cubic metres/ha.
-
Reports
with manure applied but where rates cannot be calculated from information provided.
Message:
We do not have sufficient information to adjust
your fertilizer requirement for applied manure. If you need assistance in providing
the required information, consult your local agricultural office.
-
All reports with fields requiring lime and with Mg tests less
than 100.
Message:
Note that lime is required
on one or more of your fields. Recommendations are based on lime with an "Agricultural
Index" of 75. Ask your lime supplier for the Agricultural Index of their
product so that application rates may be adjusted. Dolomitic limestone (high in
magnesium) should be used to satisfy the lime requirement on fields with magnesium
tests less than 100.
-
All
reports with NR ratings for P and/or K.
Message:
NR
(No or Negative Response) ratings signify that applications of this nutrient in
fertilizer or manure may lower crop yield or quality. Phosphate additions to soils
with excessive phosphorus levels can induce zinc deficiency on soils low in zinc
and can increase the risk of water pollution. Potash additions may induce magnesium
deficiency on soils low in magnesium.
-
All reports for winter wheat and barley.
Message:
For barley and winter wheat more accurate nitrogen requirements, adjusted for
expected yield and fertilizer cost, may be obtained by referring to the cereals
section of the OMAFRA Agronomy Guide for Field Crops, Pub. 811.
-
All reports showing a requirement for lime of 5 tonne/ha
or more.
Message:
Lime recommendations in
this report are designed to provide maximum economic returns. There may be financial
situations where it is more practical to apply the lime required over two or more
years.
-
All reports with over 1/3 legume
sod plowed down.
Message:
If forage legumes
have been underseeded in cereal grains and plowed down before the next crop, the
nitrogen fertilizer applications would be reduced by only 45 kg/ha instead of
the 50 kg/ha or 110 kg/ha reduction for legume hay fields plowed down.
-
All reports for corn with pH values below 6.1.
Message:
Lime requirements for corn printed on this
report are actually the requirements for crops such as wheat or barley commonly
grown in rotation with corn. If you are growing continuous corn, no lime is required
at soil pH values above 5.5 (5.0 on clay and clay loam soils). On continuous corn
at soil pH values below 5.5 the lime requirement shown should be reduced. Check
the soil management section of the OMAFRA Agronomy Guide for Field Crops, Pub.
811.
-
All reports with soil texture C
and with hay or pasture samples.
Message:
On
coarse textured soils (texture C) available potassium can drop rapidly if large
amounts are removed in crops such as hay or silage corn. Annual soil testing is
recommended on sandy soils for such crops unless manure is applied regularly.
-
All reports with spring cereals seeded down.
Message:
For cereals seeded down, low rates of nitrogen
are recommended to allow good forage establishment. If grain production is your
main objective, use the amount of nitrogen recommended for the grain crop not
seeded down as shown in the cereals section of the OMAFRA Agronomy Guide for Field
Crops.
-
All reports for corn.
Message:
The nitrogen requirements for corn in this
report are for a 8 t/ha grain yield (40 t/ha silage). You should adjust nitrogen
requirements for soil type, previous crop, maturity zone and higher or lower expected
yields as suggested in the corn section of the OMAFRA Agronomy Guide for Field
Crops, Pub. 811. Phosphate and potash should not need adjustment for different
expected yields.
-
All reports without
manure except those with tobacco.
Message:
If you have applied manure since the last crop was harvested, or intend to apply
manure, your fertilizer requirements should be reduced as described on the back
of this form.
-
All reports with magnesium
tests of less than 20.
Message:
When magnesium
soil tests are less than 20, application of magnesium is recommended for all crops.
Dolomitic ground limestone is the best source where the soil pH is below 6.5.
At higher pH values apply 30 kg soluble magnesium per hectare.
-
Reports for tobacco with magnesium tests between 20 and 30.
Message:
When magnesium soil tests are below 30, application of magnesium
is recommended for tobacco. Dolomitic ground limestone is the best source where
the soil pH is below 6.5. At higher pH values apply 30 kg soluble magnesium per
hectare.
-
All reports showing hay/pasture 1/3 to 1/2 legume.
Message:
Nitrogen is recommended for hay or pasture
1/3 to 1/2 legume to increase yields. It will tend to depress legume growth due
to competition from grass.
-
All reports
showing no requirement for phosphate and/or potash but without NR ratings.
Message:
Where no phosphate or potash requirements are shown, you should
not expect an economic response from applying them.
-
All reports
for winter cereals.
Message:
Fertilizers drilled
with the seed of winter cereals should not contain urea or DAP (18-46-0) and should
not supply more than 15 kg nitrogen (N)/ha.
-
All
reports with manure where time of application is not shown.
Message:
The amount of manure nitrogen available to crops depends on time
of application. See appropriate OMAFRA crop recommendation bulletin for nitrogen
adjustments.
-
All reports
with fields requiring lime and with magnesium tests of 100 or greater.
Message:
Note that lime is required on one or more of your
fields. Recommendations are based on lime with an "Agricultural Index"
of 75. Ask your lime supplier for the Agricultural Index of their product so that
application rates may be adjusted. On fields with magnesium tests of 100 or greater,
either calcitic or dolomitic lime may be used.
-
