Baconer Pig slaughtered at about 80 kg live weight (60 kg carcass) to produce bacon and ham.
Bacteria Microscopic single celled organisms occurring everywhere in nature, but important because they can cause important diseases in plants and animals. Some types of bacteria can also be beneficial. They areof importance in soil, where they break down organic matter into plant nutrients.
Bacterial stain Discoloration arising from the exudation of bacteria present in a fleece under conditions of high temperature and humidity.  Most stains are unscourable.
Bacteriophage A virus that attacks bacteria.
Bad Debt Amount due on an open account that has been proved to be un-collectable.
Bail A frame for holding an animal, e.g. milking bail, head bail.
Bail-head An adjustable wooden or metal structure at the end of a crush for locking in a beast's neck. When locked, the bail-head confines the animal for inspection or veterinary work.
Bail-up To capture, corner or restrain an animal, e.g. to bail up a wild pig.
Balance See Account balance.
Balance Day Adjustment Accounting entry made at the end of each accounting period to achieve a proper allocation of revenues and expenses to the relevant accounting period.
Balance of payments The difference between credit and debit transactions that can be worked out for an individual or for a nation. The transactions for a nation are divided into current account and capital account.  A nation is said to have either: (1) a balance of payments deficit if it sends abroad less in goods, services, and capital than it receives from foreigners; or (2) a balance of payments surplus if it sends abroad more in goods, services, and capital than it receives.
Balance of trade The difference in value between a country's merchandise imports and exports in a specified period. A country's balance of trade is only one factor, though an important one, in its balance of payments.
Balance Sheet  A statement of an entity's financial position at a point in time. It summarises the values of resources claimed by the entity and the claims on those resources by creditors and proprietors, where assets = liabilities + owner's equity. (Statement Of Assets And Liabilities)
Bale A package of material, e.g. hay bale, wool bale.  To bale up is to make into a bale.
Wool: A full wool pack weighing from 150 to 204 kg.
Baler Machine for: a) Pressing wool into large bags (bales) after shearing. b) Pressing hay or even silage into square or round bales after cutting and drying the pasture material.

Bank Account  An account kept at a bank or similar institution into which funds are deposited and from which funds are drawn, usually as cash or by cheque.
Bank Overdraft  Credit may be obtained from bank on overdraft, whereby customers arrange with their bank to overdraw their account up to an approved limit. Interest is charged on the daily balance and the borrower pays only for the funds actually in use, (however an unused limit fee may apply). The bank retains the right to cancel the arrangements at any time. The banks normally require periodic reductions of the debt and tend to prefer advance business which attracts deposit funds. Arrangements are flexible and open to renegotiation and in practice advances often become medium rather than short. The average duration of rural overdrafts appears to be about 4-5 years. Purpose of advances includes property purchase and improvements, machinery and livestock purchase, annual working expenses.
Bank reconciliation The process of checking a cash book balance against the bank statement balance. Where a check of balances shows a difference, then the bank's balance may have to be adjusted for un-presented cheques or deposits to reconcile it with the cash book balance.

Bare tramlines provide a firm compacted zone for running machinery and no crop is damaged during post-seeding operations. Bare tramlines are very visible for in-crop guidance.
Bark (Trees) All tissue outside the vascular cambium.  In older trees it may be divided into dead outer bark and living inner bark (usually consisting of phloem).
Bark (Sheep & Cattle Dogs) To give "tongue", "noise", or "speak" on command to frighten and drive the stock.

A bill is given by the drawer, and addressed to the drawee, who becomes the acceptor by writing his name across the face of the bill. The bill is payable to the payee, who must be named or indicated with reasonable certainty. If the payee is a fictitious or non-existent person the bill may be treated as payable to bearer. A bill of exchange is a negotiable instrument. A bill presently payable (e.g.. Payable at sight) or payable in the future is known as a Bill Payable, one to be received a Bill Receivable.

Biological Efficiency Level of output per unit of input, i.e. productivity, wool per sheep (kilograms per sheep), crop yields (tonnes per hectare) and liveweight gain (kilograms per head per year).
Biological Feedbacks Are common in agricultural systems and will often act to reduce substantially the yield of crop or animal product that is obtained. Immediate feedbacks in a biological system might include the cyclical fluctuations in feeding activity of animals. Longer term feedbacks can occur when animals have, say, a higher reproductive rate in one year which, through the extra demands of lactation and stress of higher grazing pressure, results in a lower mating weight and hence lower reproductive rate in the following year.

Biomining The use of micro-organisms to extract metals and minerals from ores in the mining process. Ores of high quality are rapidly being depleted and biomining allows environmentally friendly ways of extracting metals from low-grade ores (ores that have small amounts of valuable metals scattered throughout).
