D.T.Brown's Green Manure Collection

 


Green Manure Seed Collection    The great value collection includes 6 seed packets, 1 each of the following varieties:

Crimson CloverA fast growing weed suppressant and great for beneficial insects, crimson clover is an excellent nitrogen 'fixer'. Ideally dig in just before it flowers. Works very well in exposed areas. Sow: March-August Dig in: March-September. Packet will cover approx 7 sqm Not the 20sqm (24sq yards) as stated on the web site for the collection as the pack weight is only 14g

Lucerne (Alfalfa)A deep rooting nitrogen fixer which will reach down and improve the sub-soil. If desired it can be left for a year or more before being dug in. Sow: April-July Dig in: April-August. 100g Packet will cover approx 20sqm (24sq yards).

Mustard (White)Perfect for soils lacking organic matter, it grows on most soil types and produces large amounts of green matter and fibre and will help structure and moisture retention. Helps hold valuable nutrients and is ready for digging-in in only 4 to 8 weeks from sowing. Sow: March-September Dig in: March-November. Packet will cover approx 20sqm (24sq yards).

Phacelia tanacetifoliaWinter hardy so can be over wintered. Ideal for adding humus content to impoverished soils. Sow: March-September Dig in: March-November. Packet will cover approx 20sqm (24sq yards).

Winter RyeOne of the very best over-wintering green manures. Soil structure is greatly improved through the abundance of fibrous roots produced and nutrient retention is improved in wet weather. Sow: February-March or August-November Dig in: February-December. Packet will cover approx 20sqm (24sq yards).

Mustard CalienteFast growing green manure that improves soil structure and fertility. Adds organic matter and nutrients, giving the soil optimum health by suppressing weeds, soil pest and diseases. Sow: March-July or September-October Dig in: February-December. Packet will cover approx 70sqm (84sq yards).

The incorporation of green plant tissue into the soil is an ancient practice known as ‘green manuring’. Green Manures are used to disrupt pest and disease life cycles, improve soil fertility and nutrient levels and suppress weeds.

What I found disappointing is that no details regarding the coverage or the weight is to be found on any of the packs of Green Manure provided in the collection. 


Coverage Area & Pack Weight should in my humble opinion be added to all the packs. 

 

The information can be found on the products web page. 

So based on a bed size of 2.4m x 1.2m = 2.88 sq. m

 

Crimson Clover only covers 7 sq.m thus 7/ 2.88 = 2.43 Beds, so may as well say just 2 beds and split the 14g pack in half 14/2 = 7 g


Lucerene (Alfalfa), Mustard (White), Winter Rye Pack coverage = 20 sq.m 

Thus 20 / 2.88 = 6.944 beds per pack, say 7 beds 

So with a pack weighing 100g I can measure out 7 equal quantities and have enough for one bed so that I'm not too heavy handed and have the correct coverage.  

100g / 7beds = 14.29g / bed  


Phacelia Tanacetifolia pack is only 33g and also covers 20 sq.m so

33g /  7 Beds = 4.71g / bed 


Mustard Caliente pack is 100g but covers 70 sq.m 

Thus 70 / 2.88 = 24.3 say 24 beds!!! Now that's value for money  

100g / 24 beds = 4.166g / bed.
